Abstract
The most widely used and accessible monosaccharides have a number of stereogenic centers that have been hydroxylated and are challenging to chemically separate. As a result, the task of regioselective derivatization of such structures is particularly difficult. Considering this fact and to get novel rhamnopyranoside-based esters, DMAP-catalyzed di-O-stearoylation of methyl α-l-rhamnopyranoside (3) produced a mixture of 2,3-di-O- (4) and 3,4-di-O-stearates (5) (ratio 2:3) indicating the reactivity of the hydroxylated stereogenic centers of rhamnopyranoside as 3-OH > 4-OH > 2-OH. To get novel biologically active rhamnose esters, di-O-stearates 4 and 5 were converted into six 4-O- and 2-O-esters 6-11, which were fully characterized by FT-IR, 1H, and 13C NMR spectral techniques. In vitro antimicrobial assays revealed that fully esterified rhamnopyranosides 6-11 with maximum lipophilic character showed better antifungal susceptibility than antibacterial activity. These experimental findings are similar to the results found from PASS analysis data. Furthermore, the pentanoyl derivative of 2,3-di-O-stearate (compound 6) showed better antifungal functionality against F. equiseti and A. flavus, which were found to be better than standard antibiotics. To validate the better antifungal results, molecular docking of the rhamnose esters 4-11 was performed with lanosterol 14α-demethylase (PDB ID: 3LD6), including the standard antifungal antibiotics ketoconazole and fluconazole. In this instance, the binding affinities of 10 (-7.6 kcal/mol), 9 (-7.5 kcal/mol), and 7 (-6.9 kcal/mol) were better and comparable to fluconazole (-7.3 kcal/mol), indicating the likelihood of their use as non-azole type antifungal drugs in the future.

Abstract
Colorectal carcinoma (CRC) is one of the major public health problems. Vascular endothelial growth factor (VEGF) is an effective angiogenic factor and plays a pivotal role in the development, progression and metastasis of CRC. It also could further help in selecting patients of high risk of disease progression for adjuvant therapy. Therefore, this study was undertaken to reveal the importance of angiogenic factor (VEGF) as an adjunctive tool with histologic parameters of CRC. Total 45 cases were included in this cross-sectional observational study, performed in the department of Pathology, Mymensingh Medical College, Mymensingh and Immunohistochemistry was done in the department of Pathology, Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh from March 2019 to February 2021. All the cases were evaluated for VEGF immunohistochemical expression. Majority of cases were low grade adenocarcinoma (86.9%) and most common stage was stage III (48.9%). Among 45 cases collectively 13 (4-negative + 9-weak positive) cases were low for VEGF expression and 32 (22-moderate positive + 10-strong positive) cases were high for VEGF expression. Statistically significant association was found with VEGF expression and increasing tumor stage as well as with lymph node metastasis (p<0.05). VEGF had positive significant correlation with stage (r=0.322; p=0.031) of tumor. However, no correlation with VEGF expression and grade (r=0.219; p=0.149) and other clinicopathological parameters of tumor was seen.

Abstract
Breast cancer is the most common diagnosed cancer in female over the world. It is the most important cause of 'cancer death' among female. For diagnosis of breast masses the Fine needle aspiration cytology (FNAC) is applied as the primary tool. Though it is an easy, rapid and comparatively minimally invasive and inexpensive procedure for quick diagnosis, it is largely a subjective tool. Computer-assisted image morphometry provides a new influential method for high-precision measurement of nuclear features and can help to differentiate between benign and malignant breast aspirates. Therefore, the aim of study was to evaluate computer assisted semi-automatic nuclear morphometry on cytology of breast lesions to differentiate benign and malignant lesions of breast. Total 70 cases were included in this cross sectional study, performed in the department of Pathology, Mymensingh Medical College, Mymensingh, Bangladesh from March 2019 to February 2021. Morphometric analysis was done on images captured from FNAC slides of the selected cases. Image J Morphometric Software was used for image analysis. Statistical analysis was done by using SPSS 26.0 version. On analysis of morphometry, four nuclear size parameters, two nuclear shape parameters and one nuclear chromasia parameter were measured. The cut-off values with sensitivity and specificity between benign and malignant category for mean nuclear area were 61.54μm², 91.0%, 97.0%, for mean maximum feret diameter 10.89μm, 94.0%, 95.0%, for mean minimum feret diameter 7.71μm, 94.0%, 97.0% and for mean nuclear perimeter 33.32μm, 94.0%, 95.0% respectively. So, in this observation, morphometry is adjunctive tools which may overcome the limitations of inter observer agreement, improve diagnostic accuracy and avoid unnecessary repeat Fine Needle Aspiration (FNA) in breast aspirates.

Abstract
The receptor-binding domain (RBD) of SARS-CoV-2 spike (S) protein plays a vital role in binding and internalization through the alpha-helix (AH) of human angiotensin-converting enzyme 2 (hACE2). Thus, it is a potential target for designing and developing antiviral agents. Inhibition of RBD activity of the S protein may be achieved by blocking RBD interaction with hACE2. In this context, inhibitors with large contact surface area are preferable as they can form a potentially stable complex with RBD of S protein and would not allow RBD to come in contact with hACE2. Peptides represent excellent features as potential anti-RBD agents due to better efficacy, safety, and tolerability in humans compared to that of small molecules. The present study has selected 645 antiviral peptides known to inhibit various viruses and computationally screened them against the RBD of SARS-CoV-2 S protein. In primary screening, 27 out of 645 peptides exhibited higher affinity for the RBD of S protein compared to that of AH of the hACE2 receptor. Subsequently, AVP1795 appeared as the most promising candidate that could inhibit hACE2 recognition by SARS-CoV 2 as was predicted by the molecular dynamics simulation. The critical residues in RBD found for protein-peptide interactions are TYR 489, GLY 485, TYR 505, and GLU 484. Peptide-protein interactions were substantially influenced by hydrogen bonding and hydrophobic interactions. This comprehensive computational screening may provide a guideline to design the most effective peptides targeting the spike protein, which could be studied further in vitro and in vivo for assessing their anti-SARS CoV-2 activity.

Abstract
BACKGROUND & AIMS β-hydroxy-β-methylbutyrate (HMB) is purported as a key nutritional supplement for the preservation of muscle mass in health, disease and as an ergogenic aid in exercise. Of the two available forms of HMB (calcium (Ca-HMB) salt or free acid (FA-HMB)) - differences in plasma bioavailability have been reported. We previously reported that ∼3 g oral FA-HMB increased muscle protein synthesis (MPS) and reduced muscle protein breakdown (MPB). The objective of the present study was to quantify muscle protein metabolism responses to oral Ca-HMB. METHODS Eight healthy young males received a primed constant infusion of 1,2 13C2 leucine and 2H5 phenylalanine to assess MPS (by tracer incorporation in myofibrils) and MPB (via arterio-venous (A-V) dilution) at baseline and following provision of ∼3 g of Ca-HMB; muscle anabolic (MPS) and catabolic (MPB) signalling was assessed via immunoblotting. RESULTS Ca-HMB led a significant and rapid (<60 min) peak in plasma HMB concentrations (483.6 ± 14.2 μM, p < 0.0001). This rise in plasma HMB was accompanied by increases in MPS (PA: 0.046 ± 0.004%/h, CaHMB: 0.072 ± 0.004%/h, p < 0001) and suppressions in MPB (PA: 7.6 ± 1.2 μmol Phe per leg min-1, Ca-HMB: 5.2 ± 0.8 μmol Phe per leg min-1, p < 0.01). Increases in the phosphorylation of mTORc1 substrates i.e. p70S6K1 and RPS6 were also observed, with no changes detected in the MPB targets measured. CONCLUSIONS These findings support the pro-anabolic properties of HMB via mTORc1, and show that despite proposed differences in bioavailability, Ca-HMB provides a comparable stimulation to MPS and suppression of MPB, to FA-HMB, further supporting its use as a pharmaconutrient in the modulation of muscle mass.

Abstract
Abstract
Background
The aims of this prospective population-based cohort study were to identify the patient and hospital characteristics associated with emergency cholecystectomy, and the influences of these in determining variations between hospitals.
Methods
Data were collected for consecutive patients undergoing cholecystectomy in acute UK and Irish hospitals between 1 March and 1 May 2014. Potential explanatory variables influencing the performance of emergency cholecystectomy were analysed by means of multilevel, multivariable logistic regression modelling using a two-level hierarchical structure with patients (level 1) nested within hospitals (level 2).
Results
Data were collected on 4744 cholecystectomies from 165 hospitals. Increasing age, lower ASA fitness grade, biliary colic, the need for further imaging (magnetic retrograde cholangiopancreatography), endoscopic interventions (endoscopic retrograde cholangiopancreatography) and admission to a non-biliary centre significantly reduced the likelihood of an emergency cholecystectomy being performed. The multilevel model was used to calculate the probability of receiving an emergency cholecystectomy for a woman aged 40 years or over with an ASA grade of I or II and a BMI of at least 25·0 kg/m2, who presented with acute cholecystitis with an ultrasound scan showing a thick-walled gallbladder and a normal common bile duct. The mean predicted probability of receiving an emergency cholecystectomy was 0·52 (95 per cent c.i. 0·45 to 0·57). The predicted probabilities ranged from 0·02 to 0·95 across the 165 hospitals, demonstrating significant variation between hospitals.
Conclusion
Patients with similar characteristics presenting to different hospitals with acute gallbladder pathology do not receive comparable care.

Abstract
Cutaneous manifestations of visceral carcinomas are scarce, occurring in around 0.7-12% of internal malignancies. Lung cancer is one of the most common sources of skin metastasis, particularly in male patients. We present a case of cutaneous metastasis in a man with concurrent lung lesions and a previously treated colorectal carcinoma. Immunohistochemistry markers for both skin and lung lesions were strongly positive for carcinoembryonic antigen and cytokeratin 20, suggesting an intestinal primary tumour. However, colonoscopy excluded new and metastatic bowel lesions. After multidisciplinary team meetings, which reviewed the clinical, radiological and immunohistochemistry findings, it was concluded to be a non-small cell lung cancer with skin metastasis. This case presented an interesting diagnostic challenge, and highlighted the importance of cross-specialty liaison and investigation to reach the correct diagnosis.

Abstract
Maintenance of skeletal muscle mass is contingent upon the dynamic equilibrium (fasted losses–fed gains) in protein turnover. Of all nutrients, the single amino acid leucine (Leu) possesses the most marked anabolic characteristics in acting as a trigger element for the initiation of protein synthesis. While the mechanisms by which Leu is ‘sensed’ have been the subject of great scrutiny, as a branched-chain amino acid, Leu can be catabolized within muscle, thus posing the possibility that metabolites of Leu could be involved in mediating the anabolic effect(s) of Leu. Our objective was to measure muscle protein anabolism in response to Leu and its metabolite HMB. Using [1,2-13C2]Leu and [2H5]phenylalanine tracers, and GC-MS/GC-C-IRMS we studied the effect of HMB or Leu alone on MPS (by tracer incorporation into myofibrils), and for HMB we also measured muscle proteolysis (by arteriovenous (A–V) dilution). Orally consumed 3.42 g free-acid (FA-HMB) HMB (providing 2.42 g of pure HMB) exhibited rapid bioavailability in plasma and muscle and, similarly to 3.42 g Leu, stimulated muscle protein synthesis (MPS; HMB +70%vs. Leu +110%). While HMB and Leu both increased anabolic signalling (mechanistic target of rapamycin; mTOR), this was more pronounced with Leu (i.e. p70S6K1 signalling ≤90 min vs. ≤30 min for HMB). HMB consumption also attenuated muscle protein breakdown (MPB; −57%) in an insulin-independent manner. We conclude that exogenous HMB induces acute muscle anabolism (increased MPS and reduced MPB) albeit perhaps via distinct, and/or additional mechanism(s) to Leu.

Abstract
Among the marine toxins related to human intoxication, tetrodotoxin has been known as one of the most prejudicial. Two tetrodotoxins, namely PFT-1 and PFT-2 were isolated and purified from liver of puffer fish by thin layer chromatography. The structure of both the toxins was elucidated by means of IR, 1H-NMR and 13C-NMR and mass spectroscopy. Sub acute toxicity study showed that both the toxins had pronounced effects on total RBC, WBC, platelet and ESR. Further serum levels of SGPT, SGOT, SALP, bilirubin, creatinine and urea are also affected by the toxins. The histopathological examinations showed that all the tissues such as liver, lung, heart and kidney of rat were severely changed after treatment with the toxins. The toxicity of the purified compounds, PFT-1 and PFT-2 were also performed by brine shrimp lethality bioassay.

Abstract
The study was carried out to investigate the primary drug resistance pattern of tubercle bacilli isolated from the pulmonary tuberculosis patient attended in Shyamoli TB clinic, Dhaka. Sputum from 961 suspected tuberculous patients were randomly collected and stained by Ziehl-Neelsen (Z.N) stain. 135 were microscopically positive for Acid Fast Bacilli (AFB). Among them 30 patients were excluded from the study as they received antitubercular treatment before. So only 105 microscopically positive cases were cultured on Lowenstein-Jensen (L-J) media and 100 showed pure growth and rest 5 were contaminated with fungus. These 100 cases were studied on 4 antitubercular drugs. Out of these 100 isolates, 91 were M. tuberculosis and rest 9 in the nonchromogen group of mycobacteria other than tuberculosis (MOTT) species. Among 91 M. tuberculosis species, 89 (97.80%) to Isoniazid (INH), 73 (80.21%) to Rifampicin (RMP) and 91 (100%) to Streptomycin (SM) and Ethambutol (ETHM) were sensitive. Of the 9 MOTT species, 4 (44.44%) to SM, 7 (77.78%) to ETHM were sensitive and all (100%) were resistant to INH and RMP. Among the 100 isolates, 27 (18 M. tuberculosis and 9 MOTT) were resistant to 4 drugs either single or in combination. Of the 18 (66.67%) M. tuberculosis species, 16 (59.26%) to RMP, and 2 (7.41%) to RMP and INH were resistant. Of the 9 (33.33%) MOTT species, 4 (14.81%) to RMP and INH, 3 (11.11%) to RMP, INH and SM and 2 (7.41%) to RMP, INH, SM and ETHM were resistant.

Abstract
We studied 125 clinically suspected septicemic neonates (Patient) aged from 1 to 28 days and 25 healthy neonates (control) of comparable age and sexes. Cultures of blood were done and serum immunoglobulins (IgG, IgA) were estimated in all the subjects. Blood cultures were found positive in 45 (36%) patients. Preterm patients showed significantly higher number of positive blood cultures as compared to term patients. The mean serum IgG level in patients was found significantly lower than that of the controls. The serum IgG levels were also found significantly lower in 75 preterm as compared to 50 term, and in 45 blood culture positive patients as compared to 80 blood culture negative patients. On the other hand, the mean serum IgM level in patients was found significantly higher as compared to controls. Similarly, serum IgM levels were found higher in preterm patients as compared to term patients and in blood culture positive patients as compared to blood culture negative patients. No significant difference of mean serum IgA level was found among the subjects. It is evident from our study, that blood culture positive patients were mostly preterm, in whom transplacental passage of IgG is insufficient and due to low IgG level, preterm baby cannot counteract bacterial invasion and as such, suffer from septicemia more frequently. Septicemic neonates as a rule showed higher level of serum IgM due to synthesis by themselves in primary response to infection.

Abstract
Twenty two cases were studied for early detection of Xerophthalmia by impression cytology and Rose Bengal staining. Patients were below 6 years of age and admitted in the paediatric ward of Dhaka Medical College Hospital. Assessment were done by conjunctival impression cytology and staining with 1% Rose Bengal dye. Estimation of serum retinol level was done by HPLC to correlate conjunctival findings with biochemical status. The mean age of the subjects were 3.15 +/- 1.75. Rose Bengal staining was positive in 40% cases and impression cytology was in 60% cases. The mean serum retinol level of the diseased children were 10.5 +/- 3. ug/dl. The sensitivity of Rose Bengal staining was 53.3% and that of impression cytology was 80% in detecting vitamin A deficiency when compared with serum retinol level. The specificity of Rose Bengal staining was 40% and that of impression cytology was 100%. Sensitivity of impression cytology was 100% in patient with retinol level 10 ug/dl.

Abstract
A field experiment was conducted to determine the optimum shade level and nitrogen fertilizer for quality Bangladhonia (Eryngium foetidum L.) production at the Bangahandhu Sheikh Mujibar Rahman Agricultural University (BSMRAU) Research Farm during December 2002 to May 2003. The treatments consisted of four shade levels (0, 25, 50, and 75% shades) and five nitrogen rates (0, 115, 138, 161, and 184 kg N/ha). Shades were artificially created by using nylon nets of different mesh sizes and colours. Fifty percent shade and application of 161 kg N/ha independently as well as in combination gave the maximum fresh yield of Bangladhonia. β-carotene and vitamin C contents in Bangladhonia leaves were maximum in full sun light (0% shade) followed by 25 and 50% shade. Application of 161 kg N/ha produced the highest amount of β-carotene and vitamin C followed by 184 kg N/ha. The lowest amount of leaf fibre (1.30%) was recorded from 75% shade closely followed by 50% shade (1.76%), whereas the maximum amount of leaf protein was found at 50% shade. Application of 184 kg N/ha gave the highest amount of leaf protein and less leaf fibre that was followed by 161 kg N/ha. The results revealed that Bangladhonia performed better in terms of fresh yield and quality under 25-50% shade condition. Key Words: Bangladhonia; shade; nitrogen; yield; quality.
