Anticipating a wide range of morphological variations of arterial anatomy of foregut derivatives beyond the classical pattern, a precise understanding is pertinent to preoperative diagnosis, operative procedure and to avoid potentially devastating post-operative outcome during various traumatic and non-traumatic vascular insult of foregut. The study aimed to revisit the morphological details and update unusual configurations of arteries of foregut to establish clinico-anatomical correlations. This study described the detailed branching pattern of coeliac trunk (CT) as principal artery of foregut with source & course of hepatic, gastric, duodenal and pancreatic branches in 58 cadaveric dissections. Based on morphology, different types and subtypes were made. The descriptions were explained using figures and pertinent tables. Among classical branches of CT, splenic artery was found as most stable whereas other two branches were found to be most variable with missing common hepatic artery in 11 cases. In addition to classical trifurcation (65.52%), different types of bifurcation (12.07%) and tetrafurcations (22.41%) of CT were observed. Regarding variations of hepatic arteries (27.59%), both non-classical origin and accessory hepatic branches were found. In case of gastric branches, more variant origins were seen with right gastric (50%) as compared to left gastric artery (34.48%). Other morphological variations included non-classical origin of gastro-duodenal artery (18.96%) along with presence of accessory pancreatic (17.13%) and duodenal arteries (6.38%). Awareness of anatomical variations regarding circulatory dynamics of foregut is worth knowing in order to facilitate successful planning of surgery involving upper abdominal organs with least complications.

Purpose:
Acute pancreatitis (AP) is common among children in Bangladesh. Its management depends mainly on risk stratification. This study aimed to assess the severity of pediatric AP using computed tomography (CT).
Methods:
This cross-sectional, descriptive study was conducted in pediatric patients with AP at the Department of Pediatric Gastroenterology and Nutrition, BSMMU, Dhaka, Bangladesh.
Results:
Altogether, 25 patients with AP were included, of whom 18 (mean age, 10.27±4.0 years) were diagnosed with mild AP, and 7 (mean age, 10.54±4.0 years) with severe AP.Abdominal pain was present in all the patients, and vomiting was present in 88% of the patients. Etiology was not determined. No significant differences in serum lipase, serum amylase, BUN, and CRP levels were observed between the mild and severe AP groups. Total and platelet counts as well as hemoglobin, hematocrit, serum creatinine, random blood sugar, and serum alanine aminotransferase levels (p>0.05) were significantly higher in the mild AP group than in the severe AP group (p=0.001). The sensitivity, specificity, positive predictive value, and negative predictive value of CT severity index (CTSI) were 71.4%, 72.2%, 50%, and 86.7%, respectively. In addition, significant differences in pancreatic appearance and necrosis were observed between the two groups on CT.
Conclusion
CT can be used to assess the severity of AP. In the present study, the CTSI effectively assessed the severity of AP in pediatric patients.

Aims:
The main objective of the present study was to study the diversity of endophytic fungi from Ruta graveolens, an important medicinal plant. The alkaloids produced by this plant have been used in many medical applications. The endophytic fungi that inhabit the plants are also recognized as rich sources of secondary metabolites. This study was aimed to isolate, identify and study the diversity of endophytic fungi in R. graveolens and to screen the isolates for their antimicrobial activities.
Methodology and results :
A total of 12 different fungal genera were isolated from R. graveolens collected from various sites in and around Bangalore. The species richness and colonizing frequency of endophytic fungi in this plant are
comparatively less than other plants. This may be due to the secretion of the plant's phytochemicals, as it has antimicrobial activity and more than 120 phytochemicals in it. Screening of antimicrobial activity of all 10 isolates was done by agar well diffusion method, of which 80% of the fungal isolates could produce antimicrobials.
Conclusion, significance and impact of study
To conclude R. graveolens being a good medicinal plant along with its rich source of endophytes and their medicinal properties, can be exploited for the therapeutic applications.

Background and Objectives:
MYC, also known as an oncogenic reprogramming factor, is a multifunctional transcription factor that maintains induced pluripotent stem cells (iPSCs). Although MYC is frequently upregulated in various cancers and is correlated with a poor prognosis, MYC is downregulated and correlated with a good prognosis in lung adenocarcinoma. MYC and two other MYC family genes, MYCN and MYCL, have similar structures and could contribute to tumorigenic conversion both in vitro and in vivo.
Methods:
and Results: We systematically investigated whether MYC family genes act as prognostic factors in various human cancers. We first evaluated alterations in the expression of MYC family genes in various cancers using the Oncomine and The Cancer Genome Atlas (TCGA) database and their mutation and copy number alterations using the TCGA database with cBioPortal. Then, we investigated the association between the expression of MYC family genes and the prognosis of cancer patients using various prognosis databases. Multivariate analysis also confirmed that co-expression of MYC/MYCL/MYCN was significantly associated with the prognosis of lung, gastric, liver, and breast cancers.
Conclusions
Taken together, our results demonstrate that the MYC family can function not only as an oncogene but also as a tumor suppressor gene in various cancers, which could be used to develop a novel approach to cancer treatment.

Background:
Globally, medicinal plants are used to treat diseases like diabetes. The present study evaluates the possible antioxidant, acute oral toxicity, the in-vitro and in-vivo antidiabetic potential of the hydro-ethanolic leaf extract of Koenigia polystachya (HELeKP) against beta-cell damage in experimentally induced diabetes mellitus. The DPPH (2,2-diphenyl-1-picrylhydrazine), ABTS [2,2′-azino bis-(3-ethylbenzothiazoline-6-sulfonic acid)], H2O2 (Hydrogenperoxide), superoxide radical scavenging activity and NO (Nitric oxide) assay estimated the in-vitro antioxidant assay of HELeKP. The acute oral toxicity study was evaluated per the OECD (Organization for Economic Cooperation and Development) test guidelines 425. Diabetes was stimulated in rats with a single dose of Streptozotocin (STZ), and after confirmation of diabetes, HELeKP was given orally for 21 days. Blood/serum samples were gathered and examined for biochemical changes, while tissue samples were evaluated for histopathological alterations.
Results:
The IC50 value of the HELeKP for all the anti-oxidant assays confirms the free radical scavenging activity. The data on acute oral toxicity revealed that the HELeKP used in the study was comparatively very safe. The outcomes of the in-vivo study suggested that the extract significantly reduced (p < 0.001) the fasting glucose level in STZinduced diabetic rats. Furthermore, the lipid profile level was significantly normalized (p < 0.01, p < 0.001) in diabetic rats. The histopathological observation of the pancreas in HELeKP-treated rats showed significant beta-cell restoration.
Conclusions
Based on the outcomes of this study, the HELeKP-treated rats have significant free radical scavenging and anti-diabetic potential. Therefore, it can be recommended as a beneficial functional vegetable for consumption.

Primary growth hormone (GH) resistance or growth hormone insensitivity syndrome, also called Laron syndrome, is a hereditary disease caused by mutations in the GH receptor or in the post-receptor signaling pathway. This disorder is characterized by postnatal growth failure resembling GH deficiency. Differentiating the two conditions is necessary. We present the cases of two siblings, a 16-year-old female and a 9-year-old male, born from a consanguineous union. Both had normal birth weights with subsequent severe short stature and delayed teeth eruption, with no features suggestive of any systemic illness. Serum insulin-like growth factor 1 (IGF1) and insulin-like growth factor binding protein 3 (IGFBP3) were both low. Suspecting GH deficiency, provocative testing with clonidine was done revealing peak growth hormone >40 ng/mL in both patients. In view of low IGF1 and IGFBP3 and high GH on stimulation, IGF1 generation test was done for both siblings, with values supporting the diagnosis of GH insensitivity or Laron syndrome.

Objective:
This study aims to assess the perceived social support and to determine the coping of single mothers and compare the findings with that of married mothers. Methods: The study was conducted using the descriptive cross-sectional study design with a quantitative approach. Single mothers and married mothers in the age group of 18-45 years, residing in Shillong, Meghalaya-India and who have dependent children were considered as the universe in this study. Through purposive sampling technique a total of 60 participants were chosen out of which 30 were single mothers (study group) and 30 were married mothers (comparative group). Socio-demographic sheet was constructed for the purpose of this study, the Multidimensional Scale of Perceived Social Support and Brief COPE were administered for this study. Data was analyzed using SPSS version 25.
Results:
Mean of the total scores in perceived social support was found to be lesser in single mothers (59.60 ± 11.97) than that of married mothers (66.81 ± 7.013). This difference was statistically significant (t=2.847, p=0.006** ). In coping, it was seen that the difference was statistically significant in substance use (t=-2.10, p=0.040), emotional support (t= 2.489, p=0.016), behavioural disengagement (t=-3.400, p=0.001), venting (t=2.676, p=0.010), positive refram (t= 2.036, p=0.046) , humor (t= 2.31, p=0.024) and self- blame (t=-3.16, p=0.002).
Conclusions
This study is an attempt to better understanding of perceived social support and coping of single mothers as compared to married mothers. Therefore, this study would act as a guidance for policy makers to emphasize on these vulnerable family units and ensure that basic right to live dignity is fulfilled.

Introduction: Vitamin D deficiency and frequent infections are the two common
worldwide phenomenon among elderly. Recent studies have demonstrated that
vitamin D regulates the expression of specific endogenous antimicrobial peptides
like cathelicidin LL-37 of macrophages and neutrophils, which is active against a
broad spectrum of infectious agents. Therefore, the objective of the present study
was to determine the level of cathelicidin LL-37 in macrophages of elderly women
(classified according to serum 25(OH)D level) after exposure to Vibrio cholera
infection and to find out the effect of 1,25(OH)2D added in vitro. Methods: This study
was conducted among 40 randomly selected rural elderly women aged between
60 to 70 years of age. Their vitamin D status was assessed by the estimation
of serum 25(OH)D and classified into three groups viz. sufficient (14 members),
insufficient (13 members), and deficient (13 members). Later, their peripheral blood
mononuclear cells (PBMC) were isolated and cultured from fresh blood. 1,25(OH)2D
supplementation was given selectively at a dose of 10 ×10-8 M for 72 hours in the
culture media; then exposed to infection and screened according to the objectives of
this study. Results: Macrophages in all groups, except vitamin D deficient group,
responded significantly in terms of LL-37 release during exposure to Vibrio cholera
infection. Considering in vitro 1,25(OH)2D, supplementation responded significantly
(p<0.05) in all three groups. Conclusion: Vitamin D can be used as a prophylaxis
to enhance cathelicidin LL-37 release for all three groups as in the present study.

Obstetrics & Gynecology Science 2021;64(4):383-389
Objective:
The novel coronavirus pandemic led to the suspension of elective surgeries and the diversion of resources and manpower towards pandemic control. However, gynecological emergencies and malignancies must be addressed despite the restricted resources and the need for protective measures against COVID-19. This study aimed to determine the types of gynecological surgeries performed, difficulties encountered, and their outcomes in the setting of the pandemic.
Methods:
We performed a prospective cohort study over 6 months at a single tertiary center, including 60 women with gynecological complaints, categorized as emergencies and semi-emergencies, who underwent further surgery. Their surgical outcomes were measured through various parameters.
Results:
We found that 68.3% were emergency cases, while the rest were classified as semi-emergencies. Fibroid and adenomyosis with failed medical management (48.3%), followed by cervical intraepithelial neoplasia (10%), and malignancies (10%) accounted for the semi-emergency cases, while ruptured ectopic pregnancies (13.3%) and torsion and ovarian cysts (18.4%) comprised the emergency cases. The decision to incision time between emergency and semi-emergency cases varied widely due to the safety prerequisites during the pandemic, ranging from 1 hour in emergency cases to 48 hours in semi-emergency cases. In addition, we studied the ease of preoperative preparation, patient satisfaction, and the average number of personnel available to run the operation theaters at these times. No serious perioperative adverse events were observed in the present study.
Conclusion
In conclusion, gynecological surgeries could continue to be safely performed with all precautions in place against COVID-19 infection and related morbidities.
