Previous studies have shown that the gene is differentially expressed in Hu sheep lamb skin of different pattern types, and its expression level is significantly correlated with hair follicle indices of different pattern types, but the molecular mechanism of the differential expression of the gene remains unclear. This study investigated the effect of DNA methylation on the transcriptional expression of . Firstly, we found that the mRNA expression of the BMP7 gene and the activity of the core promoter of the BMP7 gene were upregulated after 5-Aza-Deoxycytidine-induced demethylation treatment using qRT-PCR and double luciferase reporter assay. Then, we found that the proliferation of Hu sheep DPCs in vitro was promoted after 5-Aza-Deoxycytidine-induced demethylation treatment through qRT-PCR, CCK-8, and EdU assay, and that the overexpression of DNMT1 in DPCs induced the opposite effect. In addition, the results of the cell cycle assay reveal that the percentage of cells in the S phase was increased after 5-Aza-Deoxycytidine-induced demethylation treatment, and that the percentage of cells in the S phase was decreased after overexpression of DNMT1 in DPCs. This study indicated that the differential expression of the gene in different patterns of Hu sheep lamb skin may be regulated by DNA methylation modification. In addition, DNA methylation can regulate the proliferation and cell cycle of DPCs in Hu sheep.

During ripening, 'Hass' avocado skin changes from green to purple/black. Low-temperature storage with a controlled atmosphere (CA) is the most widely used method for avocado storage; however, few studies have simulated this technology and considered the days of regular air (RA) storage prior to CA storage. Herein, the effect of delaying the storage of 'Hass' avocado (>30% dry matter) in a CA was examined. Long-term storage conditions (5 °C for 50 days) corresponded to (i) regular air storage (RA), (ii) CA (4 kPa O and 6 kPa CO) and (iii) 10 days in RA + 40 days in a CA and (iv) 20 days in RA + 30 days in a CA. Evaluations were performed during storage and at the ready-to-eat (RTE) stage. Skin color remained unchanged during storage, but at the RTE stage, more color development was observed for fruits stored under CA conditions, as these fruits were purple/black (>50%). At the RTE stage, the anthocyanin content increased, and compared to fruit under RA, fruit under a CA contained a five-fold greater content. A 20-day delay between harvest and CA storage increased the fruit softening rate and skin color development after cold storage, reducing the effectiveness of CA as a postharvest technology for extending storage life.

PURPOSE
The current study evaluated the lid margin microbiome of keratinized lid margins of patients with chronic Stevens-Johnson syndrome (SJS) and compared it with healthy controls and historically reported lid margin microbiome of patients with meibomian gland dysfunction (MGD).
METHODS
Eyelid margin swabs of 20 asymptomatic adults (mean age = 29 ± 12 years) and 10 patients with chronic SJS (mean age = 31.2 ± 14 years) with lid margin keratinization were sequenced using next generation of 16S rDNA V3 to V4 variable region. Within SJS, the keratinized lid margin microbiome was compared with adjacent eyelid skin.
RESULTS
All patients had obstructive MGD, and mean Schirmer I value was 2.8 ± 1.9 mm. The phyla were similar in two groups, whereas at the genera level, an increase in the relative abundance of Corynebacterium, Haemophilus, Azotobacter, and Afipia and a decrease of Acinetobacter was noted in SJS compared to healthy lid margins. SJS-associated microbiota displayed lesser diversity and more heterogeneity than healthy controls. The Principal Components Analysis (PCA) plot revealed wide separation in the SJS and the control groups. Correlational network analysis revealed Corynebacterium and Sphingomonas forming a major hub of negative interactions with other bacterial genera in the SJS group. Significant differences exist in the prevalent genera between keratinized lid margins and historically reported meibum microbiome of patients with MGD. In addition, the eyelid skin of patients with SJS had predominant Staphylococcus, whereas Corynebacterium and Pseudomonas were more in the keratinized lid margins compared to the eyelid skin microbiome.
CONCLUSIONS
Lid margin microbiome is significantly altered in the keratinized lid margins of patients with SJS compared to the eyelid skin of patients with SJS, normal lid margins, and patients with MGD.

Chanarin-Dorfman syndrome (CDS) is a multisystem autosomal recessive disorder due to variants of the ABHD5 gene, characterized by lipid vacuoles in the liver and leukocytes, and possible involvement of eyes, ears, skeletal muscle, and central nervous system. CDS may present with skin changes, most commonly congenital non- bullous ichthyosiform erythroderma, however erythrokeratoderma-like findings have been rarely reported in CDS patients. Herein, we report clinical, histopathological and genetic findings of four patients with CDS presenting with different clinical forms of erythrokeratoderma (three with progressive symmetric erythrokeratoderma-like features and one with erythrokeratoderma variabilis (EKV)-like features), including one patient with a novel mutation in ABHD5. Although the typical skin finding of CDS syndrome is reported as non-bullous congenital ichthyosiform erythroderma, CDS should also be in the differential diagnosis in patients with EKV-like lesions.

This study aimed to isolate and identify pathogenic bacteria in the intestinal tract, skin, and muscles of Sciades herzbergii; detect histopathological changes in the gill and liver; and use these biomarkers for the assessment of potential risks to human health. Fish were sampled during the rainy and dry seasons at two points in São Marcos Bay, Maranhão, Brazil: Ilha dos Caranguejos (IC) and Porto Grande (PG). Isolation and quantification were carried out using COLItest®. Colonies were subjected to identification and phenotypic investigation of antimicrobial resistance using Vitek®. Gill and liver samples were subjected to routine histological examination. The results indicated the presence of Klebsiella pneumoniae and Escherichia coli, the latter of which showed phenotypic resistance to norfloxacin and gentamicin. Fish caught at PG exhibited more extensive gill and liver damage than fish caught at IC. The findings suggest that histological changes in target organs of S. herzbergii may be influenced by infection with pathogenic bacteria.

BACKGROUND
Fordyce granules, sometimes referred to as Fordyce dots, are aberrant sebaceous glands that present as diminutive, non-painful, elevated lesions exhibiting a yellowish or whitish hue, measuring 1 to 3 mm in diameter, and manifesting inside the oral cavity. Likewise, these particles may also be seen in the vaginal region and inside the oral cavity.
AIM
The primary objective of the current study is to evaluate the potential association between Fordyce granules and the skin type of individuals who seek dental care at the Dental Clinics of Qassim University.
MATERIALS AND METHODS
The current cross-sectional research was undertaken at the Dental Clinics of Qassim University, with a sample of 87 patients diagnosed with Fordyce's granules. The research consisted of a heterogeneous sample of participants, including individuals of all genders, ranging in age from 18 to 85 years. The study included a comprehensive evaluation of several anatomical regions to identify the existence of Fordyce's granules. This examination was conducted by a single examiner who had undergone calibration. Additionally, the participants' skin types were established using the Baumann Skin Typing System questionnaire. The data that was gathered was afterward analyzed utilizing statistical methods via the use of SPSS software. A pre-set significance level was established at < 0.05.
RESULTS
The distribution of skin types among the study participants with Fordyce's granules were found to be oily skin (51.3%), dry skin (47.9%), sensitive skin (49.3%), and resistant skin (56.3%). The results of the research showed that there was no statistically significant correlation between the two variables, i.e. skin type and the presence of Fordyce's granules. This conclusion is supported by the increased values of 0.941 for those with oily skin and 0.785 for individuals with dry skin.
CONCLUSION
No relation between skin type and Fordyce's granules in the current study.

Randomized Controlled Trial
Vitiligo is considered an autoimmune disease, and its treatment is challenging. We assessed and compared the effect of fractional erbium:yttrium-aluminum-garnet (Er:YAG) laser-assisted delivery of platelet-rich plasma versus microneedling (Mn) with platelet-rich plasma (PRP) in enhancing skin repigmentation in localized stable vitiligo patients. In total, 40 patients with localized stable vitiligo were selected in a random manner into two similar groups (20 each). Group (A) was subjected to fractional Er:YAG laser combined with platelet-rich plasma and Group (B) was subjected to microneedling combined with platelet-rich plasma. The procedure was repeated every 2 weeks for up to 6 months. Each individual was assessed clinically utilizing Vitiligo Area Scoring Index (VASI). Fractional Er:YAG + PRP group achieved better pigmentation100% (excellent 30%, very good 15%, good 30% and satisfactory 25%) which is comparable to Mn + PRP where 80% of cases demonstrate repigmentation (20% very good, 10% good and 50% mild). When comparing the VASI scores for both groups after therapy to the baseline VASI, there was a statistically significant decrease [p = 0.001 for group(A) and 0.003 for group(B)]. Regarding the treatment side effects, there was significantly (p = 0.048) side effects among cases treated with microneedling group(B) (25%) than those fractional Er:Yag laser therapy group(A) (5%). Both forms of therapy demonstrated induction of repigmentation of vitiligo, but fractional Er:YAG laser efficacy is greater when combined with platelet-rich plasma.Clinical trials.gov identifier: NCT05511493.

A 27-year-old man with Allergic rhino sinusitis presented to our hospital in July 2020 with complaints of continuous sneezing, coughing while rising from bed for half an hour, and the same complaints repeated in the afternoon for half an hour, as well as a continuous dry cough for half an hour in the evening. He also had complaints of itching and skin rashes, particularly in his limbs. He underwent yoga (45 minutes, 5-6 days a week) including Jalaneti (a yogic cleansing technique, i.e. nasal irrigation with warm salt water for twice a week), hydrotherapy (enema using neem leaves paste mixed with water and steam bath on first day, followed by facial steam on alternate days) and Acupuncture (one session a week) for 8 months. Results showed a reduction in immunoglobulin E (IgE) levels and symptom severity suggesting that integrated yoga, hydrotherapy, and acupuncture are effective in the management of chronic allergic rhinosinusitis. All treatments were well tolerated without adverse effects. Though the result is encouraging, further studies are required with a larger sample size.

AIMS
We aimed to develop a European Organization for Research and Treatment of Cancer (EORTC) Quality of Life (QoL) module tailored for patients with advanced (resectable or unresectable stage III/IV) melanoma receiving immune checkpoint inhibitors or targeted therapy.
METHODS
Following the EORTC QoL Group module development guidelines, we conducted phases 1 and 2 of the development process. In phase 1, we generated a list of health-related (HR)QoL issues through a systematic literature review and semi-structured interviews with healthcare professionals (HCPs) and patients with advanced melanoma. In phase 2, these issues were converted into questionnaire items to create the preliminary module.
RESULTS
Phase 1: we retrieved 8006 articles for the literature review, of which 35 were deemed relevant, resulting in 84 HRQoL issues being extracted to create the initial issue list. Semi-structured interviews with 18 HCPs and 28 patients with advanced melanoma resulted in 28 issues being added to the initial issue list. Following EORTC module development criteria, 26 issues were removed, and two issues were added after review by patient advocates. Phase 2: To ensure uniformity and avoid duplication, 16 issues were consolidated into eight items. Additionally, an independent expert contributed one new item, resulting in a preliminary module comprising 80 HRQoL items.
CONCLUSION
We identified a range of HRQoL issues (dry skin, xerostomia, and arthralgia) relevant to patients with stage III/IV melanoma. Future module development phases will refine the questionnaire. Once completed, this module will enable standardized assessment of HRQoL in patients with (locally) advanced melanoma.

OBJECTIVE
Garlic skin (GAS) has been proven to improve the growth performance of fattening sheep. However, the mechanism by which GAS affects fattening sheep is not yet clear. The aim of this study is to investigate the effects of adding GAS to feed on the growth performance, rumen and fecal microbiota, serum and urine metabolism, and transcriptomics of rumen epithelial cells in fattening sheep.
METHODS
GAS with 80 g/kg dry matter (DM) was added to the diet of fattening sheep to study the effects of GAS on gut microbiota, serum and urine metabolism, and transcriptome of rumen epithelial tissue in fattening sheep. Twelve Hu sheep (body weights; BW, 23.0 ± 2.3 kg and ages 120 ± 3.5 d) were randomly divided into two groups. The CON group was the basal diet, while the GAS group was supplemented with GAS in the basal diet. The trial period was 10 weeks, with the first 2 weeks being the pre-trial period.
RESULTS
The daily average weight gain of fattening sheep in the GAS group was significantly higher than that in the CON group ( < 0.05), and the serum GSH-Px of the GAS group fattening sheep was significantly increased, while MDA was significantly reduced ( < 0.05). Based on the genus classification level, the addition of garlic peel in the diet changed the intestinal microbial composition, and the relative abundance was significantly upregulated by ( < 0.05), while significantly downregulated by , , and ( < 0.05). Metabolomics analysis found that there were 166 significantly different metabolites in serum and 68 significantly different metabolites in urine between the GAS and CON groups ( < 0.05). GAS had an impact on amino acid metabolism, pyrimidine metabolism, methane metabolism, riboflavin metabolism, and unsaturated fatty acid synthesis pathways ( < 0.05). Transcriptome sequencing showed that differentially expressed genes were mainly enriched in immune regulatory function, improving the health of fattening sheep.
CONCLUSION
Adding GAS can improve the energy metabolism and immune function of fattening sheep by altering gut microbiota, metabolome, and transcriptome, thereby improving the growth performance of fattening sheep.
