Association between neutrophil to lymphocyte ratio with the severity of coronary artery diseases

Background: Coronary artery disease is a type of heart disease where the arteries of the heart cannot deliver enough oxygen-rich blood to the heart. This study aimed to evaluate the association between neutrophil to lymphocyte ratio (NLR) with the severity of coronary artery diseases. Methods: This cross-sectional study was conducted in the Department of Cardiology, Chittagong Medical College Hospital, Chattogram, Bangladesh during the period from 1 July 2020 to 31 June 2021. 160 patients undergoing elective coronary angiography with the symptoms of coronary artery disease were enrolled in this study. A purposive sampling technic was used. The association between NLR and Gensini score was assessed using Pearson’s or Spearman’s correlation analysis as appropriate. All data were processed, analyzed and disseminated by using MS Excel and SPSS version 23.0 program as per necessity. Results: The mean (±SD) Gensini score of our participants was 42.75 (±29.50) and the mean (±SD) NLR (Neutrophil-lymphocyte ratio) was 2.38 (±1.11). In this study, the AUROC for NLR was found as 0.851 with a P-value of <0.001, indicating a statistically significant association of NLR with the severity of CAD. The scatter dot diagram showed the correlation between NLR and Gensini score. Both the variables were positively correlated and the degree of correlation was found statistically significant (r=0.44; p<0.001) by Pearson’s correlation test. The multivariate logistic regression analysis showed that a high level of NLR had an independent association with severe CAD (with OR being 3.308) along with dyslipidemia. Conclusion: High blood NLR is associated with the severity of CAD and it may be useful for predicting angiographically severe disease

Association of serum uric acid level with angiographic severity of coronary artery disease: a study in a tertiary care hospital, Chittagong, Bangladesh

Background: Coronary artery disease (CAD) is a major global health issue. Serum uric acid (SUA), a byproduct of purine metabolism, is linked to CAD development and progression. Elevated SUA levels are an independent risk factor for cardiovascular mortality and may indicate endothelial dysfunction. The aim of the study was to the observed associate serum uric acid level with the angiographic severity of CAD. Methods: This observational study was conducted at Chittagong medical college hospital in Bangladesh from October 2020 to September 2021. It included 130 patients and used unpaired t-tests to analyze the association between serum uric acid level and angiographic severity of CAD patients. Ethical clearance was obtained from the institutional review board of Chittagong medical college and hospital. Results: A study of 130 patients found a significant relationship between serum uric acid (SUA) levels and CAD (CAD), vessel involvement, and CAD severity (p=0.001). Patients with CAD had higher SUA levels (mean 5.26±1.32 mg/dL) compared to those without CAD (mean 4.22±1.03 mg/dL). A SUA level range of 3.94-6.58 mg/dL was associated with CAD presence. Gender also showed a highly significant association with SUA levels (p=0.001), while age, BMI, and smoking status did not show significant differences. Conclusions: A strong positive association has been found between serum uric acid level and the severity of CAD. The findings of this study approve the effectiveness of hyperuricemia as an emerging risk factor for CAD

In Vitro Anticancer Properties of Novel Bis-Triazoles

Here, we describe the anticancer activity of our novel bis-triazoles MS47 and MS49, developed previously as G-quadruplex stabilizers, focusing specifically upon the human melanoma MDA-MB-435 cell line. At the National Cancer Institute (NCI), USA, bis-triazole MS47 (NCS 778438) was evaluated against a panel of sixty human cancer cell lines, and showed selective, distinct multi-log differential patterns of activity, with GI50 and LC50 values in the sub-micromolar range against human cancer cells. MS47 showed highly selective cytotoxicity towards human melanoma, ovarian, CNS and colon cancer cell lines; in contrast, the leukemia cell lines interestingly showed resistance to MS47 cytotoxic activity. Further studies revealed the potent cell growth inhibiting properties of MS47 and MS49 against the human melanoma MDA-MB-435 cell line, as verified by MTT assays; both ligands were more potent against cancer cells than MRC-5 fetal lung fibroblasts (SI > 9). Melanoma colony formation was significantly suppressed by MS47 and MS49, and time- and dose-dependent apoptosis induction was also observed. Furthermore, MS47 significantly arrested melanoma cells at the G0/G1 cell cycle phase. While the expression levels of Hsp90 protein in melanoma cells were significantly decreased by MS49, corroborating its binding to the G4-DNA promoter of the Hsp90 gene. Both ligands failed to induce senescence in the human melanoma cells after 72 h of treatment, corroborating their weak stabilization of the telomeric G4-DNA

Seed cleaning and washing on grain quality of rice

Effect of seed cleaning and washing were studied for their effect on total grains/ear, chaffy grains/ear, spotted grains/ear and grain quality of rice var. BR 11 (Mukta). Seedlings were _raised in seedbed and the field experiments were conducted in four different locations of Sadar Upazilla of Mymensingh viz i) Field laboratory, Department of Plant Pathology, BAU, Mymensingh, ii) Barara, iii)'Sphila and iv) Raghabpur. Sorting of the harvested seeds revealed that T2 (farmer's cleaned seed), T3 (Farmer's seed washed with water), T4 (Farmer's seed washed with brine water) and T5 (farmer's seed cleaned and 'mashed with water) significantly resulted higher percent of best seeds (47.15% -57.49%) over the use of farmer's saved seed (T1), Seed cleaning, cleaning followed by washing also resulted significant number of total grains/ear and reduced number of chaffy grains/ear. From the present findings it is well focused on the importance of seed Cleaning and washing for controlling seed borne pathogens of rice

AN ETHNOBOTANICAL SURVEY OF MEDICINAL PLANTS USED BY THE CHAK TRIBAL COMMUNITY OF BANGLADESH

The Chaks are a small tribal community inhabiting the Chittagong Hill Tracts forest region in southeastern Bangladesh. They are sometimes confused with the Chakmas, who form the largest tribal group in the region. Unlike the Chakmas, the Chaks have little association with settlers from outside their community. For curing of diseases, they rely on their own traditional medicinal practitioners, who serve as priests and experts on medicinal plants. Since little is known about the medicinal plants of this tribe, we conducted an ethnobotanical survey to learn more about their use of plants, which are quite diverse in the region. Interviews of Chak traditional healers were conducted in their own language and detailed information on usage of plant species to treat various ailments was noted. Plant specimens were photographed, collected and identified at the Bangladesh National Herbarium. A total of 47 plant species belonging to 31 families were collected. The major families included Leguminosae (five plants), Rubiaceae (four plants) and Asteraceae, Convolvulaceae and Labiatae families (three plants each). The diseases for which the various plants or plant parts were used included scabies, eczema, boils, abscess, ringworm, ear disorders, jaundice, stomach pain, intestinal worms, dysentery, bloating, acidity, constipation, throat ache, pneumonia, cough, mucus, tonsillitis, fevers and pains, urinary disorders like burning sensation during urination and frequent urination, as well as rheumatism, menstrual pain, vertigo, vomiting, toothache, wounds, bone fractures, impotency, tumor, cancer, snake, animal and insect bites, malaria, frequent thirsts, edema, kidney stones, allergy and elephantitis

Chemical Composition, Antibacterial, Antioxidant and in Vitro Antidiabetic Activities of Essential Oils from Eruca vesicaria

This work describes the study of the chemical composition and bioactivity of the essential oils (EOs) of the different organs (leaves, flowers, stems and roots) from Eruca vesicaria. According to the GC and GC/MS analysis, all the EOs were dominated by erucin (4-methylthiobutyl isothiocyanate) with a percentage ranging from 17.9 % (leaves) to 98.5 % (roots). The isolated EOs were evaluated for their antioxidant (DPPH, ABTS and β-carotene/linoleic acid), antibacterial and inhibitory property against α-amylase and α-glucosidase. Most EOs exhibited an interesting α-glucosidase and α-amylase inhibitory potential. The roots essential oil was found to be the most active with IC50 values of 0.80±0.06 and 0.11±0.01 μg mL-1 , respectively. The essential oil of roots exhibited the highest antioxidant activity (DPPH, PI=92.76±0.01 %; ABTS, PI=78.87±0.19; and β-carotene, PI=56.1±0.01 %). The isolated oils were also tested for their antibacterial activity against two Gram-positive and three Gram-negative bacteria. Moderate results have been noted by comparison with Gentamicin used as positive control
