Anti-hyperglycemic and anti-hyperlipidemic effects of a methanolic extract of Debregeasia salicifolia in Alloxan-induced diabetic albino mice

Abstract Diabetes mellitus (DM), an endocrine syndrome characterized by high blood glucose levels due to abrogated insulin activity. The existing treatments for DM have side effects and varying degrees of efficacy. Therefore, it is paramount that novel approaches be developed to enhance the management of DM. Therapeutic plants have been accredited as having comparatively high efficacy with fewer adverse effects. The current study aims to elucidate the phytochemical profile, anti-hyperlipidemic, and anti-diabetic effects of methanolic extract D. salicifolia (leaves) in Alloxan-induced diabetic mice. Alloxan was injected intraperitoneally (150 mg kg-1, b.w), to induced diabetes in mice. The mice were divided into three groups (n=10). Group 1 (normal control) received normal food and purified water, Group II (diabetic control) received regular feed and clean water and group III (diabetic treated) received a methanolic extract of the plant (300 mg kg-1) for 28 days with a typical diet and clean water throughout the experiment. Blood samples were collected to checked serum glucose and concentration of LDL, TC, TG. The extract demonstrated significant antihyperglycemic activity (P 0.05), whereas improvements in mice's body weight and lipid profiles were observed after treatment with the extract. This study establishes that the extract has high efficacy with comparatively less toxicity that can be used for DM management.

Resumo Diabetes mellitus (DM) é uma síndrome endócrina caracterizada por níveis elevados de glicose no sangue devido à atividade anulada da insulina. Os tratamentos existentes para o DM têm efeitos colaterais e vários graus de eficácia. Portanto, é fundamental que novas abordagens sejam desenvolvidas para aprimorar o manejo do DM. As plantas terapêuticas foram acreditadas como tendo eficácia comparativamente alta com menos efeitos adversos. O presente estudo visa elucidar o perfil fitoquímico, efeitos anti-hiperlipidêmicos e antidiabéticos do extrato metanólico de D. salicifolia (folhas) em camundongos diabéticos induzidos por aloxana. Alloxan foi injetado por via intraperitoneal (150 mg kg-1, b.w), para induzir diabetes em camundongos. Os camundongos foram divididos em três grupos (n = 10). Grupo 1 (controle normal) recebeu ração normal e água purificada, Grupo II (controle diabético) recebeu ração regular e água limpa, e o grupo III (tratamento diabético) recebeu extrato metanólico da planta (300 mg kg-1) por 28 dias com uma dieta típica e água limpa durante todo o experimento. Amostras de sangue foram coletadas para verificar a glicose sérica e a concentração de LDL, TC, TG. O extrato demonstrou atividade anti-hiperglicêmica significativa (P 0,05), enquanto melhorias no peso corporal e no perfil lipídico dos camundongos foram observadas após o tratamento com o extrato. Este estudo estabelece que o extrato tem alta eficácia com comparativamente menos toxicidade e pode ser usado para o controle do DM.

Advancements in Genetic Diversity and Genome Characteristics of Durians (Durio spp.)

Durian is one of the important fruit crops in Southeast Asia with its unique flavor and important economic benefits. Breeding programs have produced hundreds of different cultivars of durian. These cultivars are classified mainly by fruit and flower characteristics, which cannot be observed at the vegetative stage. Therefore, molecular biology is a powerful tool to approach and explore the genetic characteristics of durians. Many studies based on barcoded DNA and molecular markers have been conducted and valuable data have been exploited. Thanks to the advancement of sequencing technology, the plastid genome and the whole genome were sequenced in some durian cultivars. The data revealed reliable data on the structure and function of several genes. This review aims to update recent studies on the durian genome attributes and potential applications in the conservation of germplasm, authentication, and exploration of the gene structure and function of this specialty plant.

PERINEOTOMY CARE AFTER CHILDBIRTH

Every woman who became pregnant has to undergo the process of delivery. In normal process of delivery the baby is delivered per vagina, an episiotomy is performed by health care provider or midwife. Episiotomy is a surgically planned incision on the perineum and the posterior vaginal wall during the second stage of labour to enlarge the vaginal introits so as to facilitate easy and safe delivery of the fetus. Episiotomy may be advice in the situations such as inelastic perineum, fetal distress, and complicated birth, prolonged second stage of labor, instrumental vaginal delivery and previous perineal surgeries .There are four types of episiotomy: midline, mediolateral, lateral and J shaped. Care of episiotomy involves perineal care, sitz bath, infrared heat, perineal exercises, antiseptic ointments, cold and hot packs The REEDA scale is used for assessing the perineal healing. Complications of episiotomy include perineal discomfort, perineal pain, difficulty with breast feeding and walking, perineal bleeding, infection, wound dehiscence and dyspareunia

Toxicity and larvicidal activity on Aedes aegypti of citronella essential oil submitted to enzymatic esterification / Toxicidade e atividade larvicida sobre Aedes aegypti de óleo essencial de citronella submetido à esterificação enzimática

Abstract The essential oil of citronella (Cymbopogon winterianus) has several biological activities, among them the insect repellent action. Some studies showed that cinnamic acid esters can be applied as natural pesticides, insecticides and fungicides. In this context, the objective of the present work was to evaluate the production of esters from citronella essential oil with cinnamic acid via enzymatic esterification. Besides, the essential oil toxicity before and after esterification against Artemia salina and larvicidal action on Aedes aegypti was investigated. Esters were produced using cinnamic acid as the acylating agent and citronella essential oil (3:1) in heptane and 15 wt% NS 88011 enzyme as biocatalysts, at 70 °C and 150 rpm. Conversion rates of citronellyl and geranyl cinnamates were 58.7 and 69.0% for NS 88011, respectively. For the toxicity to Artemia salina LC50 results of 5.29 μg mL-1 were obtained for the essential oil and 4.36 μg mL-1 for the esterified oils obtained with NS 88011. In the insecticidal activity against Aedes aegypti larvae, was obtained LC50 of 111.84 μg mL-1 for the essential oil of citronella and 86.30 μg mL-1 for the esterified oils obtained with the enzyme NS 88011, indicating high toxicity of the esters. The results demonstrated that the evaluated samples present potential of application as bioinsecticide.

Molecular detection of oral Trichomonas tenax in periodontal disease patients by polymerase chain reaction -based 18S rRNA gene

@#Trichomonas tenax, an oral flagellated protozoon found in humans, potentially associated with the inflammation of periodontal tissues and decreased immunity that causes the tissue damage and tooth loss from chronic infection. Currently, there is a lack of data regarding the prevalence of T. tenax infection in Thailand. Therefore, this study aimed to measure prevalence of T. tenax in periodontal disease patients by using polymerase chain reaction (PCR) to amplify the 18S ribosomal RNA (18S rRNA) gene and to determine the factors associated with the presence of this protozoan. A cross-sectional descriptive study was conducted among 230 patients with periodontal disease, who visited the oral health center of Suranaree University of Technology Hospital, Thailand from 2021 to 2022. Dental plaque specimens were collected and examined to identify the presence of T. tenax using the PCR-based 18S rRNA gene. The occurrence of factors associated with T. tenax infection was analyzed by the chi-square test and binary logistic regression. The prevalence of T. tenax infection was 13.48% (31/230), in patients, including 96.77% (30/31) and 3.23% (1/31) in periodontitis and gingivitis patients, respectively. The presence of T. tenax was associated with periodontal disease (p<0.001) and the Periodontal Screening and Record (PSR) index (p=0.001). The significant risk factors for T. tenax infection were periodontitis (ORadj=239.89, 95% CI=23.801-2417.746), no-underlying disease (ORadj=0.31, 95% CI=0.099–0.942), and male sex (ORadj=0.25, 95% CI=0.062-0.981). Dentists should be concerned about this oral protozoan in periodontitis patients. Furthermore, epidemiologic studies of T. tenax are still needed to investigate the mechanism of pathogenesis from T. tenax infection.

Chlorogenic acid derived from Moringa oleifera leaf as a potential antiinflammatory agent against cryptosporidiosis in mice

@#Cryptosporidiosis is a serious illness in immunodeficient patients, and there is still no drug that can completely remove the parasite from the host. The present study represents the first report investigating the impact of the active molecule chlorogenic acid (CGA), naturally isolated from Moringa oleifera leaf extract (EMOLE), on immunosuppressed, Cryptosporidium parvum-infected BALB/c mice. Mice were divided into five groups: normal mice, infected immunosuppressed mice, and infected immunosuppressed mice treated with EMOLE, CGA, and nitazoxanide (NTZ) drugs. Parasitological, immunological, and histopathological investigations were recorded besides differences in the mice’ body weight. Infected control mice showed elevated levels of oocyst shedding throughout the study. The EMOLE- and CGA-treated groups showed 84.2% and 91.0% reductions in oocyst shedding, respectively, with no significant difference compared to the drug control. The inflammatory markers IFN-γ, IL-6, IL-1β, and TNF-α were significantly higher in the infected control group. Treatment with 300 mg/kg/day of EMOLE or 30 mg/kg/day of CGA significantly downregulated pro-inflammatory cytokine levels compared to the infected group, although they did not change significantly compared to the NTZ-treated group. Histopathology of intestinal sections showed inflammatory and pathological changes in the infected control group. Low-grade tissue changes and an obvious improvement in villi structure were seen in mice treated with CGA. This study highlighted the role of CGA, isolated and purified from EMOLE, as an effective anti-inflammatory agent in eradicating C. parvum infection.

Physiological and Subjective Measures of Anxiety with Repeated Exposure to Virtual Construction Sites at Different Heights

Background@#Occupational workers at altitudes are more prone to falls, leading to catastrophic outcomes. Acrophobia, height-related anxiety, and affected executive functions lead to postural instabilities, causing falls. This study investigated the effects of repeated virtual height exposure and training on cognitive processing and height-related anxiety. @*Methods@#Twenty-eight healthy volunteers (age 20.48 ± 1.26 years; mass 69.52 ± 13.78 kg) were recruited and tested in seven virtual environments (VE) [ground (G), 2-story altitude (A1), 2-story edge (E1), 4-story altitude (A2), 4-story edge (E2), 6-story altitude (A3), and 6-story edge (E3)] over three days. At each VE, participants identified occupational hazards present in the VE and completed an Attitude Towards Heights Questionnaire (ATHQ) and a modified State-Trait Anxiety Inventory Questionnaire (mSTAIQ). The number of hazards identified and the ATHQ and mSTAIQ scores were analyzed using a 7 (VE; G, A1, A2, A3, E1, E2, E3) x 3 (DAY; DAY 1, DAY 2, DAY 3) factorial repeated measures analysis of variance. @*Results@#The participants identified the lowest number of hazards at A3 and E3 VEs and on DAY 1 compared to other VEs and DAYs. ATHQ scores were lowest at G, A1, and E1 VEs. @*Conclusion@#Cognitive processing is negatively affected by virtual altitudes, while it improves with short-term training. The features of virtual reality, such as higher involvement, engagement, and reliability, make it a better training tool to be considered in ergonomic settings. The findings of this study will provide insights into cognitive dual-tasking at altitude and its challenges, which will aid in minimizing occupational falls.

Oral parasitic protozoan Entamoeba gingivalis in periodontal disease patients, northeastern Thailand

@#Entamoeba gingivalis is present in the oral cavity of humans and is associated with periodontal disease. Consequently, this study aimed to comprehensively investigate the E. gingivalis infection and the associated risk factors among individuals suffering from periodontal conditions. A cross-sectional descriptive study was carried out within a cohort of periodontal patients. Dental plaque specimens were meticulously collected and subsequently subjected to thorough examination using the polymerase chain reaction (PCR)-based technique targeting the small subunit ribosomal RNA (SrRNA) gene of the organism. The occurrence of risk factors for E. gingivalis infection was analyzed by the chi-square test and binary logistic regression. Out of the 230 participants, 60 were clinically diagnosed with periodontitis, while 170 were afflicted with gingivitis. Out of the 230 patients, 25 (10.9%) tested positive for E. gingivalis infections. An in-depth analysis unveiled that a significant majority of infections were recorded within subgroups characterized by a marital status (15.45%), manifestation of periodontitis (25.00%), and concomitant presence of underlying disease (20.83%). Furthermore, the high risk factor associated with E. gingivalis infection was the female (ORadj = 13.65, 95% CI = 1.08-173.21), followed by periodontitis (ORadj = 3.30, 95% CI = 1.21-9.00), respectively. The study employs a molecular diagnostic approach to screen for E. gingivalis enrichment within a subset of periodontal patients with advancing disease. The findings emphasize the necessity for further research to elucidate the pathogenesis of E. gingivalis and advocate for vigilant surveillance within a substantial population of periodontal patients.

Molecular identification of Opisthorchis viverrini among the northeastern Cambodian population by internal transcribed spacer 2 based polymerase chain reaction

@#The southeast Asian fluke Opisthorchis viverrini remains endemic, particularly in Thailand, Lao PDR, Cambodia, Vietnam, and Myanmar. However, there is a lack of data on the prevalence of liver fluke infection in Kratie Province in northeastern Cambodia. The present study aimed to detect O. viverrini DNA in fecal specimens by using the internal transcribed spacer 2 (ITS2) region of ribosomal DNA (rDNA) based on polymerase chain reaction (PCR). The prevalence and percentage of O. viverrini infection were described by data analysis. Bivariate binary logistic regression analysis was used to look at the related prevalence of O. viverrini infection. A total of 6.89% from 377 fecal samples were found positive of O. viverrini DNA. The prevalence of O. viverrini infection was found to be higher in men (8.92%) than in women (5.45%), and to be associated more frequently with younger age groups (13.40%), illiteracy (8.74%), participation in other careers (non-specific occupations) (11.63%), and residence in the Trapaing Srae village (9.94%) of the Snuol district, Kratie Province. Age groups under 20 years old were significantly linked with O. viverrini infection, with ORadj=0.601, 95% CI=0.410-0.882, p=0.009 and significant value established at (P<0.05). This study demonstrates that O. viverrini infection is distributed in rural areas located near freshwater reservoirs. Therefore, active surveillance, clinical examination of association with hepatobiliary, cholangiocarcinoma, and health education are needed.

However, mild belching reappeared, and after the termination-cum-booster session belching subsided till discharge and the first follow-up after 2 weeks

Histopathological Approach To The Diagnosis Of Benign Peripheral Nerve Sheath Tumors At Uncommon Location

PARIPEX - INDIAN JOURNAL F RESEARCH |O December - 202Volume - 11 | Issue - 12 | 2 | PRINT ISSN No. 2250 - 1991 | DOI : 10.36106/paripex ABSTRACT Peripheral nerve sheath tumors are relatively common lesions that exhibit a wide morphological and biological spectrum. In the presence of classical morphological and immunohistochemical features, the histological diagnosis is usually straightforward, but they may represent diagnostic challenges. Schwannoma is a slow growing encapsulated tumor of neuroectodermal derivation that originates from the Schwann cells of the neural sheath. Most commonly presents as cerebellopontine angle mass but extracranial sites are known and needs to be considered in the differential diagnosis. Intraparotid and penile schwannomas are extremely rare. Their diagnosis could be missed on cytology due to cystic changes. Isolated plexiform neurofibroma of the tongue is again a rare tumor. Plexiform pattern recognition is important for the pathologist as these varients might show malignant transformation. Overall Fine needle aspiration cytology though inconclusive at times, help a lot initially to delineate between benign Vs malignant lesions. Moreover its minimally invasive so can be performed easily at the uncommon locations. Histopathology remains the gold standard. Clinicopathological and imaging correlation is must for definite diagnosis and treatment.

Prevalence, clinical profile, and stroke risk of atrial fibrillation in rural Andhra Pradesh, India (the AP-AF study)

The burden of atrial fibrillation (AF) is increasing worldwide. It is often asymptomatic, with stroke being the first manifestation in some. AF burden in the community and the practice of stroke prophylaxis has not been studied in India. The problem might be higher in rural regions due to poor health awareness and challenges to healthcare access. This study aimed to estimate the prevalence of AF, clinical profile and stroke risk in rural India. Methods: This is a community-based cross-sectional study done in rural Andhra Pradesh (AP). Adults from 40 villages formed the study population. We did a door-to door survey to collect information on demographics, and medical history. Electrocardiogram was recorded using a smart phone based Alivecor device. Participants diagnosed with AF underwent echocardiogram. Study cardiologists assessed the cardiovascular risk profile and collected detailed medical history. Results: Fourteen of the 4281 individuals screened had AF (0.3%). The mean age of the sampled population was 44 ± 16.5 years with 56% women. The mean age of participants with AF was 71 ±7.8 years; males were 71%. Except for one, all were non-valvular AF. Majority had a CHA2D2S2Vasc score of 2. Three had history of stroke. Two were on anticoagulant therapy but without INR monitoring. Conclusion: The prevalence of AF is lower in this study compared to studies from the developed countries. Non-rheumatic cardiovascular risk factors were primary causes for AF. Non-adherence to stroke prophylaxis is a major threat that needs to be addressed

Co-Relation of Risk Factors for Surgical Site Infection in Patients Undergoing Surgery For Carcinoma of Breast

Background: Breast malignancy is one of the highest ranked malignancy occurring among Indian females, overall incidence being 25 per 1, 00,000 females varying across different states. Breast cancer surgeries are one of the commonest surgeries being conducted which is considered to be a clean procedure pretending to be at lower risk of complications. However it is has been observed that patient develops surgical site infection at an increased rate approximately 19% which leads to poor quality of life, increased hospital stay and delay in commencement of adjuvant therapies. The aim is to Co-relate risk factors for surgical site infection in patients undergoing surgery for carcinoma of breast. The objective of this study was to observe the relation of surgical site infection and its associated risk factors in the patient undergoing surgery for carcinoma breast.Material & Methods:We analyzed 50 patients diagnosed with carcinoma breast and operated for the same in Teerthanker Mahaveer Medical College & Research Centre, Moradabad, Uttar Pradesh. Patients were divided into two groups, Group A who develop surgical site infection and Group B who don抰 develop surgical site infection. All the predisposing factors including age, BMI, Addiction, co morbidity, Neo-adjuvant therapy, preoperative total leucocyte count were recorded. An observation was done with above mentioned risk factors and correlated with development of surgical site infection.Results:In our study we found that the risk factors associated with surgical site infection post breast cancer surgeries were age, BMI, co morbidity, Addiction and Neo-adjuvant therapy.Conclusions:Patients of Age more than 50years or who underwent Mastectomy or having associated co-morbidity with co-relation to Smoking & BMI more than 30, with Increased TLC count or who have received Neo-adjuvant chemotherapy are associated with increased risk of SSI following breast surgery which has led to increased hospital stay. There are many other studies who also concluded the relation of above factors with development of SSI post breast surgery, however further research is needed to elucidate the effect of prior manipulation and radiation therapy in development of SSI.

Ethno-botanical Survey and Chemical Study of Medicinal Plants Traditionally used to Treat Anemia in Yakoma Territory (Nord Ubangi), Democratic Republic of the Congo

Aims of the Study: To identify plant species traditionally used to treat anemia in Yakoma territory and to evaluate their chemical composition. Place and Duration: Yakoma Territory (survey) and University of Kinshasa (Phytochemical study), from August and October 2019. Methods: Ethnobotanical survey according to the "snowball" sampling technique among traditional healers (based on the free consent of the respondents), chemical analyses of plant materials (chemical screening, TLC, phytomarkers content, minerals composition) according to standard methods. ED-XRF was used for mineral analysis. Microsoft Excel version 2010, Origin version 8.5 Pro and IBM SPSS statistics version 20 software packages were used for data processing and analysis. Results and Discussion: The survey showed that 18 plant species are traditionally used by Ngbandi traditional healers to treat anemia in Yakoma territory. They belong to 16 families and 17 genera. The most used organs are the leaves (68.4%) and the roots (10.5%). Decoction and infusion are the most used mode of preparation (33.3% each), followed by cooking (22.2%) and maceration (11.1%). The oral route (77.8%) is the most used mode of administration followed by the enema (16.7%) and the anal route (5.6%). Morphological types consist of herbs and trees (33.3% each) and shrubs and lianas (16.7% each). The biotope types consist of forest plants (44.4%), cultivated plants/Crops (38.9%), marshy ground plants (11.1%) and ruderal plants (5.6%). These plants belonging to five biological types: erected therophytes (44.4%), mesophanerophytes (27.8%), microphanerophytes and climbing phanerophytes (11.1% each) and lianescent phanerophytes (5.56%). These anti-anemic plant species are mostly Pantropical and Afro-tropical (39% of species each) followed by Guineo-Congolese (17% of species) and American (5%). Chemical analysis revealed the presence of alkaloids, anthocyanins, flavonoids, anthraquinones and terpenoids and various minerals including iron, zinc, copper, calcium, magnesium and manganese. Conclusion: In the current state of knowledge, the survey of anemic plants from this part of the Democratic Republic of the Congo is reported for the first time.

Performance & clinical utility of oropharyngeal versus nasopharyngeal swabs in COVID-19

Background & objectives: The oropharyngeal (OP) and nasopharyngeal (NP) swab samples are the most recommended clinical specimens for detecting SARS-CoV-2 in an individual through the quantitative real-time reverse-transcriptase-polymerase chain reaction (rRT-PCR) method. The primary objective of this study was to compare the performance of NP and OP swabs for the diagnosis of COVID-19 among 2250 concomitant samples (1125 NP + 1125 OP) using rRT-PCR test. Methods: This study was conducted at a tertiary care hospital in southern India. The study compared the specificity and efficacy of the two samples (NP & OP swabs) in 1125 individuals suspected having COVID-19 infection. The rRT-PCR values from all the samples were compared based on gender, age group and viral load. The differences between unmatched proportion and matched proportion were analysed. Agreement between the two methods was assessed using Kappa statistic. Absolute sensitivity, specificity, positive and negative predictive values (PPV and NPV) for OP and NP swabs were analysed. Results: The study identified a fair degree of agreement between OP and NP swabs in diagnosis of COVID-19 (kappa = 0.275, P<0.001). There was also a fair degree of agreement between NP and OP swabs irrespective of gender, age or duration of symptoms. NP swabs had better sensitivity and NPV as compared to OP swabs, however, specificity and PPV were 100 per cent for both. Interpretation & conclusions: The present study showed that both OP and NP swabs had similar sensitivity and specificity for predicting the presence of SARS-CoV-2.
