Identification, forensic evidences and effect of the most used lip cosmetics on the human STR profiling at Kingdom of Saudi Arabia.

This study aimed to identify the DNA STR profiles that were obtained from the lips with various lip cosmetics involved in lip pencil, lipsticks and lip gloss for a brand - Makeup Forever and lip balms (Labello brand) - have been popularly used by Saudi women at KSA. The study was involved 35 unrelated participants (healthy female donors) aged between 26 and 32. The swabbing of lip cosmetics was done prior to using them as negative control samples, other sterilized swabs were collected from the used lip cosmetics which contained the lip cells for each participant as a study sample. Moreover, the buccal swabs were firmly collected from the cleaned oral cavities for the same donors as reference samples. The air-drying of the collected swabs was done for ten minutes at room temperature and then stored them at - 20 °C before the DNA analysis. The 7500 Real-Time PCR (qRT-PCR) was quantified the extracted DNA. The amplification of 16 STR loci was done using the AmpFlSTR® Identifiler® PCR amplification kit using the Thermocycler ABI 9700 to amplify the extracted DNA. The Applied Bio-systems 3130™ Genetic Analyzer with Gene Mapper® ID-X Software v3.5 was used to analyze the PCR products. The data for quantifying DNA recorded significant decrease in the concentrations of DNA samples ranged from 0.15 to 0.55 ng/µL in comparison to the reference samples, while DNA was not detected in all the negative control samples. Some STR loci showed considerably high inhibition and low heterozygosity loss in the study samples compared to the reference and negative samples. The possibility of extracting DNA samples from lip cosmetics were used in the present study could be useful and successful in some cases due to the effect of the chemical compositions such as heavy pigments, organic components, and aromatic wax on the STR profiles in the lip cosmetics, especially in the lipsticks, lip glosses and lip pencils.

A Long-Term Follow-up Study for the Treatment of Snoring after Using Patterned Non-Ablative Erbium: YAG 2,940 nm Laser

Abstract Introduction Laser uvulopalatoplasty is an established operation for the treatment of snoring with good results on a short-term basis, while long-term follow-up studies, in addition to their scarcity, had conflicting results regarding recurrence, the change of snoring quality, and complications. Objective To assess the long-term follow-up results of using nonablative 2,940 nm Erbium: YAG for the treatment of snoring regarding outcomes and recurrence. Methods This 2-year follow-up study was conducted on 76 patients operated upon by non-ablative 2940 nm Erbium: yttrium-aluminum-garnet (YAG) using a PS01 patterned headpiece. Subjective evaluation of the treatment was performed relying on a smartphone application to record snoring in addition to a questionnaire specially designed to report recurrence and change in the quality of snoring reported by a patient's spouse. The objective evaluation was done by computed tomography (CT) imaging of the soft palate. The patients were evaluated preoperatively, 6 weeks postoperatively and after a 2-year follow-up period. Results Six week after the procedure, there was a significant improvement in 52 patients (68.4%). Out of the 52 patients, only 43 completed the 2-year follow-up; however, 15 of them complained of recurrence. Nevertheless, the patients who suffered from recurrence showed subjective improvement in snoring quality. Conclusions The nonablative mode of Erbium: YAG 2,940 nm laser proved to be efficient in soft palate tightening for the management of snoring. However, there was recurrence in 34.8% of the patients who presented objective and subjective improvement of the complaints, 6 weeks postoperatively and after a 2-year follow-up period.

Differential expression of FSHR and LHR genes and proteins during development of rabbit ovarian follicles.

The development of an ovarian follicle is a complex process at the cellular and molecular level that is mainly regulated by follicle-stimulating hormone receptor (FSHR) and luteinizing hormone receptor (LHR). To elucidate the contribution of these receptors to ovarian follicle development, it is necessary to determine their expression profiles during this biological process. Therefore, this study aimed to investigate the relationship between ovarian development pattern and the differential ovarian expression pattern of FSHR and LHR genes as well as proteins at different developmental stages. Ovaries were collected from 30 New Zealand rabbits at day 0 (birth), week 2 (neonate), week 4 (cub), week 16 (maturity), and day 18 pregnancy. Ovarian histology, and gene as well as protein expression were determined using light microscopy, real-time PCR and western blotting, respectively. The results showed that the expression levels of FSHR mRNA and protein increased coincidently with age and the growth of ovarian follicles. The levels of LHR mRNA and protein remained low from the day of birth until week 4 and became significantly higher by week 16 coinciding with appearance of growing and antral follicles, which have a defined thecal layer. FSHR gene and protein expression decreased with pregnancy, whereas LHR increased, reaching a peak level during pregnancy. It can be concluded that changes in FSHR and LHR gene and protein expression could be related to the growth and development of follicles, indicating the regulatory role for these receptors in rabbit folliculogenesis.

A Study on the Effect of 850 nm Low-Level Diode Laser versus Electrical Stimulation in Facial Nerve Regeneration for Patients with Bell's Palsy.

INTRODUCTION: Bell's palsy is acute facial paralysis with unclear etiology that results in weakness of facial muscles or paralysis on one side of the face. METHODS: This prospective, randomized, single-blind, controlled study was conducted on 45 patients with Bell's palsy who were randomly divided into three equal groups. Two groups received either low-level laser therapy (LLLT) or electrical stimulation (E.S.) both in conjunction to medications, massage, and facial exercise treatment. The third group (control) was treated with medication, massage, and facial exercise. RESULTS: The primary outcome was the improvement of nerve conduction velocity of facial nerve while the secondary outcome was the change of Sunnybrook facial grading system (SBGS). The outcome measures were evaluated pre- and posttreatment. There was statistically significant difference between the three groups in favor of the LLLT group regarding the nerve action potential amplitude and latency, in addition to signs of nerve regeneration and improved SBGS. CONCLUSION: This short-term investigation revealed that LLLT proved to be more efficient than E.S. in facial nerve regeneration for patients with Bell's palsy.

Population genetic data for 12 X-STR loci in the Central Saudi region using investigator Argus X-12 amplification kit.

BACKGROUND: X-chromosome short tandem repeat (X-STR) markers are important in forensic identity investigations and kinship analysis. SUBJECT AND METHODS: In the current study, the distribution of 12 X-STR loci located in four linkage groups was evaluated using Investigator® Argus X-12 Amplification Kit in 200 unrelated healthy individuals (105 males and 95 females) from the central region of Saudi Arabia in order to develop an allelic frequency database for the markers included in the kit. RESULTS: DXS10146 locus was the most informative with 21 alleles, while DXS8378 locus was the least with five alleles. Forensic parameters showed that all X-STRs loci, either as individual markers or as linkage groups, provide genetic information with high discrimination that is appropriate for forensic purposes with polymorphism information content (PIC), power of exclusion (PE), and paternity index (PI) varying from 0.61211 to 0.917979, 0.38722 to 0.842949, and 0.038416 to 0.16367, respectively. The pairwise genetic distance fixation index (Fst) results showed that the Saudi population is genetically closer to the Egyptian and Emirati populations and distant to the Turkish population. CONCLUSION: The current study revealed that Investigator® Argus 12 X-STR kit would support the forensic application, kinship testing involving female offspring, and human identification in the Saudi population.

The impact of chimerism on DNA-based human identification from skin surface cells of post-allogenic hematopoietic stem cell transplantation (HCST) patients.

The use of biological traces recovered from touched or handled items increased with the advance of the forensic analysis system. Thus, DNA profiles obtained from touch DNA became a useful tool in forensic investigation. However, a chimeric person with more than one chromosomal population can be challenging for a forensic analyst. We investigated the genetic profile in blood, buccal swab, and skin swabs from twenty-four recipients aged 21-63 years who underwent a matched sibling allogeneic hematopoietic stem cell transplantation with no sign of skin graft versus host disease. Autosomal short tandem repeats genotyping was performed to evaluate chimerism status at 15 loci along with gender marker Amelogenin. According to our results, donor chimerism was detected in all recipient's blood samples, while in buccal swabs, five recipients showed no presence of donor-derived cells in their genotype. Epithelial cells swabbed from hand fingertips were not devoid of donor-derived cells since all recipients showed high chimerism (39.69%-96.66%) in their genotypes. A significant change in chimerism was seen among various types of biological samples (p<0.05). No correlations were observed between chimerism and recipient age, gender, or time after transplant (p> 0.05). The loci D21S11, D8S1179, and FGA were the most informative, whereas D13S317, Vwa, and TOPX were the least informative STR markers. We concluded that touch DNA from a person who has undergone a successful allogeneic HSCTs should not be considered as reliable evidence for human identifications. Therefore, necessary precautions must be taken to avoid false identification and miscarriage of justice.

Novel Management of Rhinophyma by Patterned Ablative 2940nm Erbium:YAG Laser.

INTRODUCTION: Rhinophyma is a cosmetic disorder that causes emotional distress if the symptoms are extensive or obvious enough. Treatment options range from topical antibiotics or isotretinoin, surgical resection, cryosurgery, electrocautery, dermabrasion and more recently laser therapy. With the limitations of surgical techniques, lasers gained popularity for treating rhinophyma. However, laser ablation is invasive and can lead to side effects and prolonged downtime. Fractional photothermolysis (FP) was introduced to overcome the limitations posed by conventional ablative lasers. To the best of our knowledge, there are no previous studies to evaluate the use of Er:YAG in an ablative mode with a fractional handpiece for the treatment of rhinophyma. AIM OF THE WORK: The goal of this study was to evaluate the efficacy and safety of fractional ablative 2940 nm Er:YAG laser for the treatment of mild to moderate rhinophyma. PATIENTS AND METHODS: Sixteen patients having mild to moderate rhinophyma were treated with fractional ablative 2940 nm Er:YAG laser. All patients received 4 laser treatments and were followed up over the following 3 months. An additional follow-up appointment 6 months after the last session was arranged to detect any signs of recurrence. OUTCOME MEASURES: Patient questionnaire was used to evaluate patient subjective satisfaction. Objective evaluation was performed by a blind assessment of clinical photographs that were taken before and 3 months after the final treatment by two independent blinded evaluators. RESULTS: Patient questionnaire taken 3 months after last treatment revealed that 8 patients (50%) were "very satisfied", 4 patients (25%) were satisfied, and 4 patients (25%) were somewhat satisfied. None of the patients assessed their results as not satisfying. CONCLUSION: In conclusion, the use of patterned ablative Er:YAG laser with a PS01 handpiece and parameters used in this study comprise an effective tool for treatment of mild to moderate rhinophyma with rapid postoperative recovery compared with conventional surgical procedures and other ablative lasers.

Scanning electron microscopy and histomorphology of the epiglottis in dromedaries: A study revealing unusual structure with the probable functional role.

While epiglottis is essentially a mammalian structure, studying its microstructure in any placental model will add an important information to the field of comparative anatomy and the related branches of biology. The aim of this study was to describe the structure of the epiglottis in dromedary camels using light and scanning electron microscopy (SEM), with reference to the possible functions. A total of 11 epiglottis cartilages from 11 larynges were used. The study revealed unusual, deeply situated glands just beneath the cartilage plate. They have unusually, wide surface-openings, while their ducts were partly located within the cartilage. This is presumed to be an adaptation to the need for rapid and efficient mucosal surface hydration in the arid conditions. The possible secretion transport mechanisms in these glands were also discussed. Furthermore, the SEM revealed for the first time, the presence of taste buds in camel epiglottis. However, in histological sections, visibility of taste buds was dependent upon the staining techniques. The taste buds were not seen with standard H& E stain, as they blended imperceptibly with the surrounding epithelium. Conversely, Mallory's trichrome showed contrasting colors, and taste buds were visible. In conclusion, camel epiglottis has an unusual structure, which may be correlated to environmental adaptation and important for the general health of upper respiratory tract in this species.

Serum protein electrophoretic profile in diarrheic neonatal calves.

The electrophoretic profile of clinically healthy newborn calves and calves with neonatal diarrhea was compared. Blood samples were collected at 3 and 10 days of age from 11 calves that remained clinically healthy throughout the study period and 14 calves with diarrhea. A significant reduction in the gamma globulins was observed in the diarrheic calves that can be attributed to the transfer of serum immunoglobulins, to the intestinal lumen to counteract the infection. Moreover, a significant increase in the albumin was observed in this group between the sampling days that is mainly attributed to the relative reduction of the gamma globulin fraction.

Evaluation of Skin Surface as an Alternative Source of Reference DNA Samples: A Pilot Study.

An acceptable area for collecting DNA reference sample is a part of the forensic DNA analysis development. The aim of this study was to evaluate skin surface cells (SSC) as an alternate source of reference DNA sample. From each volunteer (n = 10), six samples from skin surface areas (forearm and fingertips) and two traditional samples (blood and buccal cells) were collected. Genomic DNA was extracted and quantified then genotyped using standard techniques. The highest DNA concentration of SSC samples was collected using the tape/forearm method of collection (2.1 ng/µL). Cotton swabs moistened with ethanol yielded higher quantities of DNA than swabs moistened with salicylic acid, and it gave the highest percentage of full STR profiles (97%). This study supports the use of SSC as a noninvasive sampling technique and as a extremely useful source of DNA reference samples among certain cultures where the use of buccal swabs can be considered socially unacceptable.

A novel management of streptococcal pharyngotonsillar infections by laser-activated silver nanoparticles and methylene blue conjugate, in vitro study.

INTRODUCTION: Species of Streptococcus are classified based on their hemolytic properties into alpha and beta types. And, since antimicrobial drug resistance is an increasingly problematic issue, the efforts to develop modalities that would overcome this obstacle and avoid antibiotic side effects is an ongoing challenge. METHODS AND MATERIALS: 20 patients from both sexes were selected. The isolated organisms were identified according to standard laboratory methods. Bacterial Cultures were subjected to the low-level diode laser (660 nm), methylene blue (MB) as a photosensitizing agent and for silver nanoparticles. RESULTS: All the experimental groups showed statistically lower values of CFU/ml than the positive control group. CONCLUSION: The photoactivated MB, silver nanoparticles conjugate showed the maximum inhibitory effect on Streptococci, which opens a gate to further investigation of such a promising protocol to establish a safe and efficient method of management for resistant cases of streptococcal tonsillar infections.

Carbon dioxide laser versus erbium:YAG laser in treatment of epidermal verrucous nevus: a comparative randomized clinical study.

BACKGROUND: A verrucous epidermal nevus (VEN) is a skin disorder that has been treated using different treatment modalities with varying results. Ablative lasers such as carbon dioxide laser (CO2) and erbium:yttrium-aluminum-garnet (Er:YAG) laser have been considered as the gold standard for the treatment of epidermal nevi. OBJECTIVE: To evaluate and compare the efficacy, postoperative wound healing and side effects of pulsed CO2 laser and Er:YAG laser for the treatment of verrucous epidermal nevi. MATERIALS AND METHODS: Twenty patients with localized VEN were randomly divided into two groups. Group 1 was administered CO2 laser and group 2 underwent Er:YAG laser treatment. A blinded physician evaluated the photographs and dermoscopic photomicrographs for the efficacy and possible side effects. All patients received one treatment session and were followed up over a 6-month period. RESULTS: Both lasers induced noticeable clinical improvement, but there were no significant differences between two lasers in treatment response, patient satisfaction, duration of erythema and side effects. The average time to re-epithelialization was 13.5 days with CO2 and 7.9 days with Er:YAG laser (p< .0005). No scarring was observed in Er:YAG laser group and no lesional recurrence was detected in CO2 laser group since treatment. CONCLUSION: Apart from re-epithelialization, both lasers showed equivalent outcomes with respect to treatment response, patient satisfaction, side effects and complications.

Expression of neuronal and non-neuronal markers in the vomeronasal organs of one-humped camel (Camelus dromedarius) and Egyptian water buffalo (Bubalus bubalis) / Expresión de marcadores neuronales y no neuronales en los órganos vomeronasales del camello jorobado y el búfalo egipcio de agua

Fourteen vomeronasal organs (VNOs) of adult males one-humped camels (Camelus dromedarius) and Egyptian water buffaloes (Bubalus bubalis) (n=7/each) were examined immunohistochemically with neuronal markers; synaptophysin (SYP) and glial fibrillary acidic protein (GFAP) to clarify the distribution of the vomeronasal (VN) receptor cells and nerve fibers, in addition to elucidate the existence of non-neuronal elements via S-100 and endothelial nitric oxide synthase (eNOS). In both animals, the VNO was lined medially with VN sensory (olfactory) epithelium and non-sensory (respiratory) epithelium laterally. Immunohistochemically, both animals showed SYP immunolabeling only in the receptor cells of VN sensory epithelium while GFAP labeled the ensheathing cells of the nerve fibers of VNOs. Both S-100 and eNOS labeled non-neuronal elements of the VNO; the supporting cells of sensory epithelium and the VN glands. In view of these observations, we postulate that the VNOs of both animals contain various cells populations that express several neuronal and non-neuronal markers. As well as, SYP and GFAP are suggested as markers for receptor cells and ensheathing cells of nerves of the VNOs respectively. However, no clear differences can be detected in the expressions of neuronal and non-neuronal markers in VNOs of camel and buffalo since they are ruminant species.

En este estudio fueron examinados 14 órganos vomeronasales (OVN) de machos adultos de camellos de una joroba (Camelus dromedarius) y búfalos egipcios de agua (Bubalus bubalis) (n = 7 / cada uno) por inmunohistoquímica con marcadores neuronales, sinaptofisina (SIP) y proteína ácida fibrilar glial (PAFG), para identificar la distribución vomeronasal (VN) del receptor de células y fibras nerviosas, además de dilucidar la existencia de elementos no neuronales a través de S-100 y óxido nítrico sintasa endotelial (ONSe). En ambos animales, el OVN se encuentra alineado en sentido medial con el epitelio sensorial (olfato) y lateralmente con el epitelio no sensorial (respiratorio). En el estudio inmunohistoquímico, ambos animales mostraron marcadores inmunológicos solamente en las células receptoras del epitelio sensorial VN, mientras que la proteína ácida fibrilar glial marcaba las fibras nerviosas de OVN. Tanto el S-100 como la óxido nítrico sintasa endotelial, marcaron elementos no neuronales del OVN, las células de revestimiento del epitelio sensorial y las glándulas VN. En relación a estas observaciones, se postula que los OVN de ambos animales contienen células que expresan varios marcadores neuronales y no neuronales. SIP y la PAFG se sugieren como marcadores para células receptoras y las células gliales de nervios del OVN, respectivamente. Sin embargo, debido a que son especies de rumiantes, no existen diferencias claras que se puedan detectar en las expresiones de los marcadores neuronales y no neuronales en el OVN de camello y búfalo.

Management of ear lobule keloids using 980-nm diode laser.

The objective of the study was to evaluate the 980-nm diode laser in conjunction with corticosteroids in the treatment of ear lobule keloids. Several methods have been described for the treatment of keloid scars, but none of them have been 100% successful. Advances in laser techniques have enabled surgeons to define the most appropriate lasers for use in the treatment of different scar types. The diode laser pulses are delivered interstitially in a single repeated mode in non-overlapping sites using a bare optical fiber, followed by intralesional triamcinolone acetonide injection. The number of sessions varies between two to five for the management of more than 75% of keloid size, with a total success rate of 75% and no recurrence in the follow-up of 12 months. The technique used proved to be effective in the treatment of ear lobule keloids.

Utilization of CO(2) laser for temporal fascia graft welding in myringoplasty: an experimental study on guinea pigs.

UNLABELLED: An experimental study was undertaken to investigate the use of a CO(2) laser welding technique in myringoplasty. Albumin solder was used to fix a temporal fascia graft via an overlay transcanal approach. The results of the operative procedure were assessed by microscopic and histopathologic examination over an interval of 1, 2, 3 and 4 weeks postoperatively. MATERIALS AND METHODS: Forty-eight adult guinea pigs were divided into two groups after permanent perforation of the tympanic membrane was created: laser-assisted myringoplasty group and surgical myringoplasty group. Laser beam power was 0.4 W, pulse duration 0.75 s, pulse interval 0.1 s and spot size 250 microm. Each experimental group was further subdivided into four subgroups of 6 animals each. Histological and microscopic findings of the tympanic membrane for both groups after 1, 2, 3, and 4 weeks were compared. RESULTS: Microscopic examination of the tympanic membrane showed high success rate in the laser-assisted myringoplasty group compared to the control group. Histological evaluation for the tympanic membrane showed complete repair of the tympanic membrane in the laser-assisted myringoplasty group. CONCLUSION: Laser-assisted myringoplasty using CO(2) might be a promising new method in surgical myringoplasty.

Effects of short inter-stimulus intervals on olfactory and trigeminal event-related potentials.

CONCLUSION: Chemosensory event-related potentials (CSERPs) were identified in all measurements using the 20 s and the 10 s inter-stimulus interval (ISI) protocol, reducing the recording time to 75% or 57% compared with the standard protocol. A possible explanation for the rising CSERP amplitudes by shortening the ISI in CO(2) stimulation is due to a phenomenon known as trigeminal sensitization during repeated stimulation. OBJECTIVES: CSERPs are influenced by the ISI. The aim of this study was to evaluate the changes in CSERPs by decreasing the ISI from 30 s to 20 s or 10 s, respectively. SUBJECTS AND METHODS: Ten normosmic healthy subjects participated this study. Phenyl ethyl alcohol (PEA), hydrogen sulphide (H(2)S) and carbon dioxide (CO(2)) were used in CSERP measurements with different ISI protocols (30 s (standard), 20 s and 10 s). Amplitudes and latencies of ISI protocols were submitted to ANOVA for repeated measurements and t tests for paired samples. RESULTS: The amplitudes of CSERPs with PEA and H(2)S stimuli were decreasing with shortening the ISI significantly. In contrast, the highest amplitudes of trigeminal CSERPs were recorded with the 10 s ISI protocol with CO(2). The ANOVA revealed a significantly different effect of shortening the ISI on CSERPs on the right and the left side.

The correlation between basal serum follicle-stimulating hormone levels before embryo cryopreservation and the clinical outcome of frozen embryo transfers.

OBJECTIVE: To evaluate the correlation between basal serum FSH level before the fresh IVF/intracytoplasmic sperm injection (ICSI) cycle and the clinical outcome of the subsequent frozen embryo replacement cycles. DESIGN: Retrospective observational study. SETTING: University tertiary referral center, London, United Kingdom. PATIENT(S): Five hundred four consecutive frozen embryo transfer (FET) cycles where serum FSH levels were obtained, on days 1-4 of the cycle before the fresh IVF +/- ICSI cycles. INTERVENTION(S): Frozen-thawed embryo transfer. MAIN OUTCOME MEASURE(S): Clinical pregnancy (CP) and live birth (LB). RESULT(S): Basal serum FSH in 127 women (25.2%) who had a CP was significantly lower compared with that in women who did not have a CP. Multivariate regression analysis showed significant correlation between basal serum FSH levels and clinical pregnancy and a low significance to LB, but there was no statistical significant differences between women who had a CP and those who did not with regard to age, treatment protocol (natural or hormone treatment cycle), or the freeze-thaw interval. The LB rate was higher in natural cycles (n = 71; 21.2%) than in hormone treatment cycles (n = 28; 16.7%). Conceiving in the fresh cycle had a positive influence on the FET outcome. CONCLUSION(S): Basal serum FSH level before fresh IVF/ICSI cycle is inversely correlated to a CP outcome in FET cycles. A trend was present between FSH levels and LB, but this failed to reach statistical significance.
