Altered Extracellular Matrix-Related Pathways Accelerate the Transition from Normal to Pre-Fibroid Myometrium in Black Women.

BACKGROUND: Black women experience a disproportionate impact of uterine fibroids compared to White women, including earlier diagnosis, higher frequency, and more severe symptoms. The etiology underlying this racial disparity remains elusive. OBJECTIVE: The aim of this study was to evaluate the molecular differences in normal myometrium (fibroid-free uteri) and at-risk myometrium (fibroid-containing uteri) tissues in Black and White women. STUDY DESIGN: We conducted whole-genome RNA-seq on normal and at-risk myometrium tissues obtained from both self-identified Black and White women (not Hispanic or Latino) to determine global gene expression profiles and to conduct enriched pathway analyses (n=3 per group). We initially assessed the differences within the same type of tissue (normal or at-risk myometrium) between races. Subsequently, we analyzed the transcriptome of normal myometrium compared to at-risk myometrium in each race and determined the differences between them. We validated our findings through real-time PCR (sample size range=5-12), western blot (sample size range=5-6), and immunohistochemistry techniques (sample size range=9-16). RESULTS: The transcriptomic analysis revealed distinct profiles between Black and White women in normal and at-risk myometrium tissues. Interestingly, genes and pathways related to extracellular matrix and mechanosensing were more enriched in normal myometrium from Black than White women. Transcription factor enrichment analysis detected greater activity of the serum response transcription factor positional motif in normal myometrium from Black compared to White women. Furthermore, we observed increased expression levels of myocardin-related transcription factor-serum response factor and the serum response factor in the same comparison. In addition, we noted increased expression of both mRNA and protein levels of vinculin, a target gene of the serum response factor, in normal myometrium tissues from Black women as compared to White women. Importantly, the transcriptomic profile of normal to at-risk myometrium conversion differs between Black and White women. Specifically, we observed that extracellular matrix-related pathways are involved in the transition from normal to at-risk myometrium and that these processes are exacerbated in Black women. We found increased levels of Tenascin C, type I collagen alpha 1 chain, fibronectin and, phospho-p38 MAPK (Thr180/Tyr182, active) protein levels in at-risk over normal myometrium tissues from Black women, whereas such differences were not observed in samples from White women. CONCLUSIONS: These findings indicate that the racial disparities in uterine fibroids may be attributed to heightened production of extracellular matrix in the myometrium in Black women, even before the tumors appear. Future research is needed to understand early life determinants of the observed racial differences.

Postoperative Hemoglobin Drop and the Associated Factors among Elective Orthopedic Surgeries in Northern Tanzania.

Background: Having an estimated level of Hb drop in different orthopedic surgeries would help plan for surgery from pre- to postoperative periods. The aim of this study was to assess the Hb drop and the associated factors during the intraoperative period among elective orthopedic surgeries. Methods: This was an analytic cross-sectional study conducted between October 2022 and March 2023, which included all patients admitted for elective orthopedic surgery who met the inclusion criteria. Data were collected before and after the patient was operated on. Information was analyzed using t-tests and ANOVA to establish the statistical significance of the Hb drop. Results: A total of 195 participants were enrolled. The majority of the participants were male (62.1%), with the main etiology of symptoms being motor traffic accidents (31.8%). The most affected site was the femur (36.4%), followed by the spine (23.6%). The highest mean Hb drop was in total hip replacement surgeries (4.19 g/dL), with the overall mean Hb drop being 2.75 g/dL. A statistically significant difference was identified in diathermy use, duration of surgery, and patients with chronic illnesses. Conclusion: With a mean Hb drop of 2.75 g/dL, the application of diathermy and surgeries with shorter durations resulted in a reduced Hb drop. These factors should be incorporated to minimize the drop in Hb in orthopedic surgeries. Accounting for differences in surgeries, there should not be delays in patients who have a preoperative Hb level that can sustain the mean Hb drop recorded in the study.

Effect of Slow Maxillary Expansion and Alternative Rapid Maxillary Expansion Protocols on Airway Volume in Cleft Palate Cases: A Cone Beam Computed Tomography Based Study.

A total of 22 patients with cleft palate aged 8 to 12 years were selected and categorized into two groups: the first group was treated with alternate rapid maxillary expansion and constriction (Alt-RAMEC) using an expander with differential opening (EDO) and facemask, while the second group was treated using slow maxillary expansion (SME) using an EDO. Finally, the pharyngeal airway volume in the two groups was compared using cone beam computed tomography (CBCT). CBCT scans were performed before expansion and six months following the expansion. Alveolar crest level, maxillary breadth, nasal cavity width, arch width, inclination of the molar teeth, buccal and palatal alveolar bone thickness, and maxillary alveolar width were all assessed. Paired t-tests (p=0.05) were applied to compare interphase data. The two groups showed a non-significant difference in terms of nasopharyngeal volume (cm3), oropharyngeal volume (cm3), and overall pre- and post-treatment results (p>0.005). Results of comparison of pre- and post-treatment periods in the Alt-RAMEC group revealed a significantly higher cleft volume (cm3) (p=0.001). Results of comparison of pre- and post-treatment periods in the SME group revealed a substantial rise in cleft volume (cm3) (p=0.003). Results from a comparison of the cleft volume (cm3) between the two study groups pre- and post-intervention revealed a non-significant difference (p=0.200 and 0.054, respectively).

Probing protein aggregation through spectroscopic insights and multimodal approaches: A comprehensive review for counteracting neurodegenerative disorders.

Aberrant accumulation of protein misfolding can cause aggregation and fibrillation and is one of the primary characteristic features of neurodegenerative diseases. Because they are disordered, misfolded, and aggregated proteins pose a significant setback in drug designing. The structural study of intermediate steps in these kinds of aggregated proteins will allow us to determine the conformational changes as well as the probable pathways encompassing various neurodegenerative disorders. The analysis of protein aggregates involved in neurodegenerative diseases relies on a diverse toolkit of biophysical techniques, encompassing both morphological and non-morphological methods. Additionally, Thioflavin T (ThT) assays and Circular Dichroism (CD) spectroscopy facilitate investigations into aggregation kinetics and secondary structure alterations. The collective application of these biophysical techniques empowers researchers to comprehensively unravel the intricate nature of protein aggregates associated with neurodegeneration. Furthermore, the topics covered in this review have summed up a handful of well-established techniques used for the structural analysis of protein aggregation. This multifaceted approach advances our fundamental understanding of the underlying mechanisms driving neurodegenerative diseases and informs potential therapeutic strategies.

The Risk of Breast Implant-Associated Anaplastic Large Cell Lymphoma; A Systematic Review and Meta-Analysis.

BACKGROUND: Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is an emerging disorder that has gained global attention throughout the past era. The present meta-analysis was performed to retrieve the risk of BIA-ALCL from population-based epidemiological studies. Factors associated with BIA-ALCL were evaluated to identify patients at higher risk of BIA-ALCL. METHODS: A systematic literature search was executed throughout 12 databases. All epidemiological studies encompassing patients with breast implants either for aesthetic or reconstructive purposes and reported the risk of BIA-ALCL were included. Studies reported the risk factors of BIA-ALCL were included. RESULTS: The present meta-analysis included 17 articles, encompassing 525,475 patients with breast implants. There were 254 patients with BIA-ALCL with a mean duration to the diagnosis of BIA-ALCL of 13.16 years (95% CI 11.7-14.6, P < 0.001). There were 44 patients with textured breast implants and two with smooth implants. Patients with breast implants were 28.86 times more at high risk of BI-ALCL (95% CI 3.123-266.681). The risk ranged from 0 to 1 per 1000 cases with breast implants, with a similar risk among patients seeking aesthetic and reconstructive surgeries. The risk was 0 to 1 case per 1000 cases among patients with textured breast implants. There was a significant association between the history of breast cancer and BIA-ALCL (P = 0.0016). CONCLUSION: This meta-analysis confirmed the association between breast implants and ALCL. There was a similar risk of BIA-ALCL among patients with aesthetic or reconstructive surgeries. Patients with a history of breast cancer were at higher risk of BIA-ALCL. LEVEL OF EVIDENCE III: This journal requires that authors assign a level of evidence to each article.

Gamma Irradiated Pasteurella multocida Vaccine induces strong humoral immunity and protects rabbits from disease.

Pasteurella multocida is affecting a multitude of animals and severely affects livestock production. Existing vaccines are mostly chemically inactivated and do not lead to wide protection. Irradiated vaccines are enjoying a renaissance and the concept of "replication defficient but metabolically active" vaccines was recently evaluated in several vaccine trials. P. multocida was isolated from the nasal swab, blood, and lung swab samples from infected rabbits. Gamma irradiation of P. multocida for inhibition of replication was evaluated at an optimized irradiation dose of 10 Kgy established. Four groups of rabbits were (mock) vaccinated with a commercial P. multocida vaccine and three irradiated formulations as liquid, lyophilized formulations with added Trehalose and lyophilized-Trehalose with an "activation" culturing the irradiated bacteria for 24 in broth. Evaluation of humoral immune response by ELISA showed that all three irradiated vaccines produced an effective, protective, and continued IgG serum level after vaccination and bacterial challenge. The IFN-γ expression is maintained at a normal level, within each individual group however, the lyophilized trehalose irradiated vaccine showed peak mean of IFN-γ titer at one week after booster dose (day 21) which was statistically significant. Cumulatively, the results of this study show that gamma-irradiated P. multocida vaccines are safe and protect rabbits against disease. Moreover, Rabbits' immunization with the three irradiated formulations avoided adverse side effects as compared to commercial polyvalent vaccine, the body weight gain for the irradiated vaccine groups indicates less stress compared to the commercial polyvalent vaccine.

Impact of the Antioxidant Hydroxytyrosol on the Quality of Post-Thawed Stallion Semen.

The objective of this study was to investigate the impact of including hydroxytyrosol (HT) antioxidant on the viability of sperm after the processes of cooling and freezing. HT antioxidants were used in the HF-20 extender at concentrations of 1.25, 2.5, 5, and 10 µg/ml. The HF-20 extender was a basic extender and was used for the control group. The post-thawed semen exhibited significantly higher total motility in the 2.5 HT and 10 HT treatment groups than the control group. The straight line velocity (VSL) of the 2.5 HT group exhibited a significantly high value compared with the control group. However, the average path velocity (VAP), linearity (LIN), straightness index (STR), and wobble (WOB) revealed identical findings across all groups. The findings of the analysis of HOST, normal morphology, major abnormalities, and minor abnormalities revealed that there were no significant differences between the HT groups and the control groups. Nevertheless, the use of HT antioxidant for freezing semen led to a notable enhancement (p < 0.05) in both acrosome integrity and vitality tests when compared to the control group. In this case, the lower quantities of HT (1.25 and 2.5 µg/ml; p < 0.05) preserve the DNA fragmentation compared with the 5 HT, 10 HT, and control groups. In conclusion, the HT antioxidant has shown the capacity to enhance the quality of frozen-thawed spermatozoa and positively influence the viability and integrity of DNA inside the frozen-thawed spermatozoa. Additional research should be conducted to assess the fertility potential of cryopreserved stallion semen.

Structural and functional characterization of the role of acetylation on the interactions of the human Atg8-family proteins with the autophagy receptor TP53INP2/DOR.

The Atg8-family proteins (MAP1LC3/LC3A, LC3B, LC3C, GABARAP, GABARAPL1 and GABARAPL2) play a pivotal role in macroautophagy/autophagy through their ability to help form autophagosomes. Although autophagosomes form in the cytoplasm, nuclear levels of the Atg8-family proteins are significant. Recently, the nuclear/cytoplasmic shuttling of LC3B was shown to require deacetylation of two Lys residues (K49 and K51 in LC3B), which are conserved in Atg8-family proteins. To exit the nucleus, deacetylated LC3B must bind TP53INP2/DOR (tumor protein p53 inducible nuclear protein 2) through interaction with the LC3-interacting region (LIR) of TP53INP2 (TP53INP2LIR). To examine their selectivity for TP53INP2 and the role of the conserved Lys residues in Atg8-family proteins, we prepared the six human Atg8-family proteins and acetylated variants of LC3A and GABARAP for biophysical and structural characterization of their interactions with the TP53INP2LIR. Isothermal titration calorimetry (ITC) experiments demonstrate that this LIR binds preferentially to GABARAP subfamily proteins, and that only acetylation of the second Lys residue reduces binding to GABARAP and LC3A. Crystal structures of complexes with GABARAP and LC3A (acetylated and deacetylated) define a ß-sheet in the TP53INP2LIR that determines the GABARAP selectivity and establishes the importance of acetylation at the second Lys. The in vitro results were confirmed in cells using acetyl-mimetic variants of GABARAP and LC3A to examine nuclear/cytoplasmic shuttling and colocalization with TP53INP2. Together, the results demonstrate that TP53INP2 shows selectivity to the GABARAP subfamily and acetylation at the second Lys of GABARAP and LC3A disrupts key interactions with TP53INP2 required for their nuclear/cytoplasmic shuttling.

Stable Clinical and Radiological Outcomes at Medium and over 5 Year follow up of Calcaneus Fracture Open Reduction Internal Fixation using a Sinus Tarsi Approach.

The Sinus Tarsi Approach is increasingly growing in popularity for open reduction internal fixation of calcaneus fractures. Multiple studies have demonstrated favorable short-term results compared to the traditional extensile L incision, however long-term data over 5 years is currently limited to a single retrospective case series. Following local ethical approval, all patients who had completed a minimum 5 years from time of operation were contacted with a standardised telephone questionnaire completed. This followed a previous retrospective chart review, with follow up telephone or clinic consultation performed by Davey et al of this cohort at mean 35 months. Thirty-four fractures (31 patients) completed minimum 5 year follow up from the eligible group of 54 fractures (49 patients). Regarding functional outcomes, a significant improvement in mean Maryland Foot Score was observed between short- (mean 35.8 months) and medium-term (mean 81.9 months) of 77.6 (SD 15.0) to 86 (SD 7.9). (p=0.0082.) There was no significant difference in postoperative and long term radiographic Bohler's angle. (p=0.9683.) Eleven feet (32%) proceeded to require reoperation, with removal of metal performed in 10 (29%), fusion in 2 (6%) and skin grafting following wound breakdown for 1 (3%). Four feet (12.9%) experienced post operative wound complications, including 3 (9.68%) cases of infection and 2 (6.45%) of delayed wound healing. This study demonstrated stable clinical and radiographic outcomes over 5 years following Calcaneus Fracture Open Reduction Internal Fixation using a Sinus Tarsi Approach, supporting its continued usage when treating intraarticular calcaneus fractures for which operative intervention is indicated.

The Monitoring of Accumulations of Elements in Apple, Pear, and Quince Fruit Parts.

In this study, the distribution of biogenic macro and micro element contents in the peel, pulp, and seeds of some cultivated fruits was observed. The element concentrations of these fruits, which have high commercial value and consumption in the world, were analyzed with ICP-OES. In the "Golden" and "Starking" apple varieties, the lowest and highest calcium amounts were detected in the pulp and seed parts of the fruits, respectively. Additionally, the lowest and highest calcium amounts of pear and quince fruits were found in the seed and pulp and peel and seed parts of the fruits, respectively. Potassium amounts of "Golden" and "Starking" apple parts were established to be between 3585.82 (seed) and 3930.87 mg/kg (pulp) and 3533.82 (peel) and 5671.55 mg/kg (pulp), respectively. Potassium amounts of pear and quince fruit parts were measured to be between 2340.65 (seed) and 5405.97 mg/kg (pulp) and 4455.23 (seed) and 8551.12 mg/kg (pulp), respectively. Iron quantities of the parts of "Golden" and "Starking" apple fruits were established from 4.80 (pulp) and 17.14 mg/kg (seed) to 7.80 (pulp) and 14.53 mg/kg (peel), respectively. While the Fe quantities of pear fruit parts are found to be between 4.51 (pulp) and 15.40 mg/kg (peel), the Fe contents of the parts of quince fruits were determined to be between 5.59 (pulp) and 27.27 mg/kg (peel). Zinc quantities of the parts of pear and quince fruits were recorded to be between 8.43 (pulp) and 12.71 mg/kg (seed) and 0.96 (pulp) and 37.82 mg/kg (seed), respectively. In fruit parts, the highest element was found in the seed, followed by pulp and peel in decreasing order.

Revolutionizing scandium detection in real samples: Unleashing the power of sol-gel-based optical sensor.

The development of a highly selective and ultra-sensitive optical sensor for detecting scandium (Sc3+) ions involves incorporating the reagent 2,3-dichloro-6-(3-carboxy-2-hydroxy-1-naphthylazo)quinoxaline (DCHNAQ) into a silica sol-gel thin film on a glass substrate. This innovative approach utilizes tetraethoxy-silane (TEOS) as the precursor, maintaining a sol-gel pH level of 4.5, a water-to-alkoxide ratio of 5:1, and a DCHNAQ concentration of 5.0 × 10-4 M. A detailed exploration of the impact of sol-gel parameters on the sensing capabilities of the developed sensor has been meticulously undertaken. This innovative sensor demonstrates remarkable selectivity in evaluating Sc3+ ions over a dynamic range of 7.5-170 ng/mL, with limits of quantification and detection recorded at 7.3 and 2.20 ng/mL, respectively. Consistent results are achieved with a minimal RSD of 1.47 and 0.94% for Sc3+ ions at 50 and 100 ng/mL, respectively, coupled with a swift response time of three min. Assessments of interference demonstrate a noteworthy preference for Sc3+ions, accomplished by enclosing DCHNAQ within the sol-gel framework and making optimal structural modifications to the doped sol-gel. The sensor offers straightforward regeneration using a 0.25 M EDTA solution, exhibiting complete reversibility. Comparative analysis with other methodologies underscores the efficacy in determining Sc3+ions in various reference materials, including plant leaves, fish, water, alloys, ores, and monazite samples.

The use of dienogest in treatment of symptomatic adenomyosis: A systematic review and meta-analysis.

Adenomyosis is a gynaecological problem that impacts women's quality of life by causing dysmenorrhea, chronic pelvic pain, and menorrhagia. The search continues for the best medical treatment for symptomatic adenomyosis. This systematic review and meta-analysis investigated the role of dienogest, an oral progestin, in reducing pain and bleeding associated with adenomyosis. Cochrane Central Register of Controlled Trials (CENTRAL), EMBASE, MEDLINE, Scopus, and Web of Science were searched in January 2024. The primary outcome was pain scores for dysmenorrhea, whereas secondary outcomes were chronic pelvic pain (CPP), uterine volume (UV), and menorrhagia. One comparison was performed comparing outcomes in symptomatic adenomyosis before and after treatment with dienogest. Pooled analysis of included studies reported a statistically significant reduction of dysmenorrhea pain score after dienogest treatment (mean difference -5.86 cm on a 10-cm visual analogue scale, 95 % CI -7.20 to -4.53, I2 = 97 %). Regarding chronic pelvic pain, a meta-analysis of included studies showed a significant decline in pain after treatment (standardized mean difference -2.37, 95 % CI -2.89 to -1.86, I2 = 60 %). However, uterine volume did not differ significantly after treatment (mean difference -4.65 cm3, 95 % CI -43.22 to 33.91). Menorrhagia was improved significantly after treatment (Peto odds ratio 0.07, 95 % CI 0.03 to 0.18). In conclusion, dienogest seems to be effective in controlling painful symptoms and uterine bleeding in women with adenomyosis at short and long-term therapy.

Eco-friendly optical sensor for precise detection of gold ions in diverse matrices through the integration of ß-2-hydroxybenzyl-3-methoxy-2-hydroxyazastyrene in a PVC membrane.

An environmentally conscious methodology is investigated for the precise and discerning identification of trace concentrations of gold ions in diverse matrices. A novel optical sensor membrane is proposed for the determination of Au3+ ions, utilizing the immobilization of ß-2-hydroxybenzyl-3-methoxy-2-hydroxyazastyrene (HMHS) entrapped in polyvinyl chloride (PVC). The sensor incorporates sodium tetraphenylborate (Na-TPB) as the ionic additive and dibutyl phthalate (DBP) as a plasticizer. Under optimal conditions, the suggested sensor exhibits a linear calibration response to Au3+ ions within a concentration range of 5.0 to 165 ng mL-1. Detection and quantification limits are specified as 1.5 and 4.8 ng mL-1, respectively, with a rapid response time of 5.0 min. Upon presentation, this optical sensor not only affirms high reproducibility, stability, and an extended operational lifespan but also showcases exceptional selectivity for Au3+ ions. Notably, no discernible interference is observed when assessing the potential influence of other cations and anions on Au3+ ion detection. The adaptability of this optical sensor is validated through its successful application in determining Au3+ ion concentrations across various sample types, including water, environmental, cosmetics, and soil matrices.

A triple kidney: Coexistence of normal left kidney and mal-rotated horseshoe anomaly: A rare case report.

The occurrence of triple kidneys, involving a normal kidney and a malrotation horseshoe kidney, is an extremely infrequent condition. This case report demonstrates a triple, mal-rotated horseshoe kidneys coexist with an upper junction stone, alongside a normal left kidney showing normal Doppler vascularity, as observed in an ultrasound examination for 18-year-old male complaints of diffuse periumbilical pain and burning micturition. Laboratory investigation revealed normal creatinine level, and presence of urinary tract infection. Management option for this case are antibiotic therapy and surgical intervention for horseshoe kidney stone. Regular monitoring of kidney function, other radiographic imaging studies, and follow-up to assess the efficacy of the treatment, and detect any further complications are essential.

Pediatric Unilateral Chronic Sinusitis: Clinical and Radiological Patterns Compared to Adults.

Introduction: Upper respiratory tract infections and sinusitis are more prevalent in children than in adults. Unilateral sinusitis is not uncommon disease. Our aim was to analyze the disease characteristics in children with unilateral sinusitis and compare them with those of adults. Materials and Methods: This study included 124 patients with unilateral chronic sinusitis divided according to age into two groups: pediatric group ≤18 years (66 cases) and adult group >18 years (58 cases). The groups were compared in terms of demographic data, side, clinical manifestations and radiological findings. Results: In pediatric patients, the most common inflammatory pathology was antrochoanal polyps, followed by allergic fungal sinusitis. On the other hand, chronic sinusitis without nasal polyps is the most common in adults, followed by antrochoanal polyps. The mean duration of clinical manifestations before diagnosis in pediatric patients was significantly shorter than that in adults (P=0.001). The most common symptoms in both pediatric and adult patients were anterior nasal discharge and nasal obstruction. Proptosis was significantly higher in pediatric group than in adult group (P=0.015). On computed tomography (CT), the most commonly affected sinus in both pediatric and adult patients was the maxillary sinus followed by the anterior ethmoid sinus. Bone expansion, erosion and involvement of adjacent structures were significantly higher in pediatric patients (P=0.028, 0.027 respectively). Conclusion: Pediatric patients have a high incidence of antrochoanal polyps and allergic fungal sinusitis as unilateral inflammatory lesions. These lesions require surgical management. Inflammatory paranasal sinus lesions in pediatric patients have a shorter duration of clinical manifestations and a higher incidence of bone erosion and involvement of adjacent structures; therefore, early diagnosis and management prevent complications.

Protective Effects of an Oligo-Fucoidan-Based Formula against Osteoarthritis Development via iNOS and COX-2 Suppression following Monosodium Iodoacetate Injection.

Osteoarthritis (OA) is a debilitating joint disorder characterized by cartilage degradation and chronic inflammation, accompanied by high oxidative stress. In this study, we utilized the monosodium iodoacetate (MIA)-induced OA model to investigate the efficacy of oligo-fucoidan-based formula (FF) intervention in mitigating OA progression. Through its capacity to alleviate joint bearing function and inflammation, improvements in cartilage integrity following oligo-fucoidan-based formula intervention were observed, highlighting its protective effects against cartilage degeneration and structural damage. Furthermore, the oligo-fucoidan-based formula modulated the p38 signaling pathway, along with downregulating cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS) expression, contributing to its beneficial effects. Our study provides valuable insights into targeted interventions for OA management and calls for further clinical investigations to validate these preclinical findings and to explore the translational potential of an oligo-fucoidan-based formula in human OA patients.

Surgical outcomes of robotic versus conventional autologous breast reconstruction: a systematic review and meta-analysis.

Breast reconstruction is an integral part of breast cancer management. Conventional techniques of flap harvesting for autologous breast reconstruction are associated with considerable complications. Robotic surgery has enabled a new spectrum of minimally invasive breast surgeries. The current systematic review and meta-analysis study was designed to retrieve the surgical and clinical outcomes of robotic versus conventional techniques for autologous breast reconstruction. An extensive systematic literature review was performed from inception to 25 April 2023. All clinical studies comparing the outcomes of robotic and conventional autologous breast reconstruction were included for meta-analysis. The present meta-analysis included seven articles consisting of 783 patients. Of them, 263 patients received robotic breast reconstruction, while 520 patients received conventional technique. Of note, 477 patients received latissimus dorsi flap (LDF) and 306 were subjected to deep inferior epigastric artery perforator (DIEP) flap. There was a significantly prolonged duration of surgery (MD 58.36;95% CI 32.05,84.67;P < 0.001) and duration of anaesthesia (MD 47;95% CI 16.23,77.77;P = 0.003) among patients who underwent robotic surgery. There was a similar risk of complications between robotic and conventional surgeries. The mean level of pain intensity was significantly lower among patients who received robotic breast surgery (MD- 0.28;95% CI - 0.73,0.17; P = 0.22). There was prolonged length of hospitalization among patients with conventional DIEP flap surgery (MD- 0.59;95% CI - 1.13,- 0.05;P = 0.03). The present meta-analysis highlighted the feasibility, safety, and effectiveness of robotic autologous breast reconstruction. This included the successful harvesting of LDF and DIEP flap with acceptable surgical and functional outcomes.

An ensemble learning model for forecasting water-pipe leakage.

Based on the benefits of different ensemble methods, such as bagging and boosting, which have been studied and adopted extensively in research and practice, where bagging and boosting focus more on reducing variance and bias, this paper presented an optimization ensemble learning-based model for a large pipe failure dataset of water pipe leakage forecasting, something that was not previously considered by others. It is known that tuning the hyperparameters of each base learned inside the ensemble weight optimization process can produce better-performing ensembles, so it effectively improves the accuracy of water pipe leakage forecasting based on the pipeline failure rate. To evaluate the proposed model, the results are compared with the results of the bagging ensemble and boosting ensemble models using the root-mean-square error (RMSE), the mean square error (MSE), the mean absolute error (MAE), and the coefficient of determination (R2) of the bagging ensemble technique, the boosting ensemble technique and optimizable ensemble technique are higher than other models. The experimental result shows that the optimizable ensemble model has better prediction accuracy. The optimizable ensemble model has achieved the best prediction of water pipe failure rate at the 14th iteration, with the least RMSE = 0.00231 and MAE = 0.00071513 when building the model that predicts water pipe leakage forecasting via pipeline failure rate.

Biochar enhances the growth and physiological characteristics of Medicago sativa, Amaranthus caudatus and Zea mays in saline soils.

Biochar is a promising solution to alleviate the negative impacts of salinity stress on agricultural production. Biochar derived from food waste effect was investigated on three plant species, Medicago sativa, Amaranthus caudatus, and Zea mays, under saline environments. The results showed that biochar improved significantly the height by 30%, fresh weight of shoot by 35% and root by 45% of all three species compared to control (saline soil without biochar adding), as well as enhanced their photosynthetic pigments and enzyme activities in soil. This positive effect varied significantly between the 3 plants highlighting the importance of the plant-biochar interactions. Thus, the application of biochar is a promising solution to enhance the growth, root morphology, and physiological characteristics of plants under salt-induced stress.

Investigation of accumulation of element contents in some wild and cultivated dried fruits.

In this study, the moisture and biogenic element quantities of most wild and cultivated edible dried fruits were investigated. Macroelements found in highest amounts in fruits were K, P, Ca, and Mg. While K quantities of the fruits are recorded between 5212.77 ("white myrtle") and 25550.60 mg/kg ("black nightshade"), P amounts of the fruits were characterized to be between 949.08 (black myrtle) and 4420.75 mg/kg ("black nightshade"). Ca and Mg amounts of the fruits were assessed to be between 359.83 (plum) and 4330.89 mg/kg ("yellow hawthorn") to 214.98 (plum) and 1852.04 mg/kg ("black nightshade"), respectively. Fe and B quantities of the fruitss were established to be between 2.69 ("black myrtle") and 60.13 mg/kg (cherry) to 3.76 ("black myrtle") and 76.25 mg/kg (sour cherry), respectively. In general, except for white and black myrtle fruits, it is thought that other fruits can be good sources of P, K, and Fe. P contents of "laurel cherry," "cherry," "black nightshade," and "Fragrant black grapes" were found partly high than those of other fruits. "Cherry laurel," "sour cherry," "cherry," "pear," "black nightshade," "black fig," and "hawthorn (yellow)" fruits contain more K than other fruits.
