ABSTRACT

The study aimed to achieve enhanced targeted cytotoxicity and cell-internalization of cisplatin-loaded deoxyribonucleic acid-nanothread (CPT-DNA-NT),mediated by scavenger receptors into HeLa cells.DNA-NT was developed with stiff-topology utilizing circular-scaffold to encapsulate CPT.Atomic force microscopy (AFM) characterization of the DNA-NT showed uniformity in the structure with a diameter of 50-150 nm and length of 300-600 nm.The successful fabrication of the DNA-NT was confirmed through native-polyacrylamide gel electrophoresis analysis,as large the molecular-weight (polymeric) DNA-NT did not split into constituting strands under applied current and voltage.The results of cell viability confirmed that blank DNA-NT had the least cytotoxicity at the highest concentration (512 nM) with a viability of 92% as evidence of its biocompatibility for drug delivery.MTT assay showed superior cyto-toxicity of CPT-DNA-NT than that of the free CPT due to the depot release of CPT after DNA-NT inter-nalization.The DNA-NT exhibited targeted cell internalizations with the controlled intracellular release of CPT (from DNA-NT),as illustrated in confocal images.Therefore,in vitro cytotoxicity assessment through flow cytometry showed enhanced apoptosis (72.7%) with CPT-DNA-NT (compared to free CPT;64.4%).CPT-DNA-NT,being poly-anionic,showed enhanced endocytosis via scavenger receptors.

ABSTRACT

Formation of stones in the gall bladder is known as cholelithiasis. About 10% to 20% of Western population are suffering from gall stones and this percentage is increasing day by day. Biochemically gall stones are classified into black pigment stones, brown pigment stones and cholesterol stones. Gall stones can be anatomically located at two possible sites; in the gall bladder known as cholelithiasis and in the common bile duct known as choledocholithiasis. Gall stones may present with symptoms known as symptomatic gallstones or without symptoms known as asymptomatic gallstones. The major causes of gallstones are high cholesterol diet, low bile salt levels, decreased gall bladder motility etc. Obesity, female gender, family history, rapid weight loss and vitamin B12 or folic acid deficiency are considered as important risk factors in the development of gall stones. The clinical presentations include acute cholecystitis and febrile illness with pain and tenderness in the right upper quadrant (Murphy sign). Generalized body weakness and weight loss are considered as generalized symptoms of gallstones. The complications include cholangitis, empyema of gall bladder, pancreatitis, abscess formation, porcelain gall bladder and gall bladder perforation. The differential diagnosis of gall stones is carried out based on endoscopy, ALT and AST serum levels. Non-surgical treatment for gall stones is oral dissolution therapy. The standard surgical treatment for gall stones is cholecystectomy.

ABSTRACT

Diabetes mellitus is a world-widely public health issue associated with premature mortality, decreased quality of life and increased health-care expenditures. The aim of the review was to elevate the effect of apple cider vinegar on glycemic control, hyperlipidemia and obesity control in type 2 diabetes patients. Many clinical trials showed the hypoglycemic, hypolipidemic and anti-obesity effect of vinegar. Proposed mechanisms action of vinegar for the hypoglycemic, hypolipidemic effect are including slow gastric emptying, it promotes uptake of skeleton muscles glucose in the body and acetic acid may inhibit disaccharides activity in the small intestine blocking the complete digestion of starch molecules, suppression of hepatic glucose production and increased glucose utilization. Results of previous studies showed that apple cider vinegar has the potential of anti-diabetic, antihyperlipidemic and antiobesity effects in diabetes mellitus patients. Objective of review: The objective of the current review study was to investigate the effect of apple cider vinegar on glycemic control, hyperlipidemia and control on body weight in type 2 diabetes patients and other therapeutic and commercial effect of apple cider vinegar. Data sources: To collect data for relevant literature PubMed, Google Scholar, science direct and Cochrane sources were used.

ABSTRACT

Aim: The aim of the trial was to measure the effect of apple cider vinegar on glycemic control and biochemical parameters in type 2 diabetes mellitus (DM) patients with poor glycemic control. Methods: A single-blind, randomized, placebo-controlled trial was conducted on 110 eligible types 2 DM patients who were selected and allocated into 2 groups. The interventional group was given 15 ml apple cider vinegar in 200 ml water during dinner for 3 months while the other group was placebo. Before and after HbA1C (glycosylated hemoglobin), fasting lipid profile, fasting blood sugar, anthropometrics, and dietary changes were assessed and analyzed using IBM SPSS version 20, through statistical tests. Formal ethical approval was obtained from the local institutional review board. Results: Significant mean change was found in interventional group in HbA1c (p<0.001), blood sugar fasting (p<0.001), total cholesterol (p=0.002), triglyceride (p=0.002) and hip-waist ratio (p=0.002). No significant change was observed in the mean of these statistics in the placebo group. No significant change was observed in height, weight, mid-upper arm ratio, and low density lipoprotein, high density lipoprotein and food frequency in intervention and placebo groups before and after. Conclusion: Apple cider vinegar if used regularly is effective in controlling diabetes, lowering hypercholesterolemia and hypertriglyceridemia in DM type 2 patients.

ABSTRACT

Introduction: The most common childhood orbital malignancy is the rhabdomyosarcoma contributing almost 10% of all RMS cases. The mean age of orbital RMS is 6-8 years and rare case of RMS from birth to the 8th decade was reported. Male are more affected as compared to female. Total 60.4% male were affected with RMS as compared to female was 39.6%. Objective: The objective of the current study was to describe a case of recurrent orbital rhabdomyosarcoma and effectiveness of chemotherapy to RMS in a 2 year old child. Methods: Computer tomography, magnetic resonance images and excision biopsy were done for confirmation of tumor. After confirmation patient was treated with chemotherapy. Results: Excision biopsy showed tumor composed of round blue cells with high nodular cells ratio and hyper chromatic nuclei and finding also presented favors of Embreyonal rhabdomyosarcoma and child was treated with chemotherapy after completion of chemotherapy course this little child was came to his normal life but after 6 months sudden symptoms of recurrence has been appeared and this time tumor was most aggressive and cannot be controlled with only chemotherapy treatment. Conclusion: To achieve a good survival rate of RMS in children and elderly age there is a need to complete surgical tumor resection in anywhere of the body. Only chemotherapy should not be helpful and cannot be preventable from recurrence. Early diagnosis and stared treatment is the best approach and any delay in diagnosis can have a negative effect on health status.

ABSTRACT

Objective:To determine the role of toll-like receptor 4 (TLR-4) in eliciting cellular and humoral immune responses against recombinant Mycobacterium bovis bacille Calmette-Guérin (rBCG) expressing the C-terminus of merozoite surface protein-1 of Plasmodium falciparum.Methods:Six groups of mice (n=6 per group) were injected with phosphate buffered saline T80,BCG or rBCG intraperitoneally,in the presence or absence of a TLR-4 inhibitor;TAK-242.Enzyme-linked immunosorbent assay was carried out for serum total IgG,IgG1,IgG2a and IgG2b determination.Spleens were also harvested and splenocytes cultured for determination of intracellular cytokines;IL-4 and IFN-γ via enzyme-linked immunosorbent assay.Results:The production of total IgG,and the subclasses IgG 1,IgG2a and IgG2b was significantly higher in rBCG-immunised mice than BCG and phosphate buffered saline immunised mice in the absence of TAK-242.A significant rise in total IgG occurred with more booster immunisations.The level of IgG2a was highest,followed by IgG2b,then IgG1.The production of both IL-4 and IFN-γ was also highest in the rBCG immunised groups.These significant rises were inhibited in the presence of TAK-242.Conclusions:We present evidence of the role of TLR-4 in the increased production of total IgG,IgG1,IgG2a and IgG2b,as well as IL-4 and IFN-γ in response to our rBCG construct.

ABSTRACT

The main objective of this study was to generate perception in community regarding pollution of heavy metals contained in Aloe vera and Tamarix aphylla plants which have wide range of medicinal use but having toxic concentration of heavy metals. The plant samples were collected at three different areas referred as spots i.e. polluted (spot 1), less polluted (spot 2) and non- polluted (spot 3) from District Kohat, Khyber Pakhtunkhwa, Pakistan. In the present study, essential heavy metals such as Cobalt (Co), Nickel (Ni), Chromium (Cr), Copper (Cu), Iron (Fe) and Zinc (Zn) and non-essential heavy metals Cadmium (Cd), Lead (Pb) were analyzed in Aloe vera leaves and Tamarix aphylla by using Flame atomic absorption spectrophotometer. Heavy metals concentration in different spots were found to be in order as Spot 1> Spot 2>Spot 3 with the concentration range of found heavy metals., Cd 0.25-0.51 mg/kg, Pb BDL-15.23, Co 1.90-3.31mg/kg, Ni 2.98-4.01 mg/kg, Cr 4.86- 6.01 mg/kg, Cu 2.32-3.01 mg/kg, Fe 12.42-22.47 mg/kg, Zn 34.53-53.08 mg/kg for Aloe vera leaves and concentrations of the same heavy metals like Cd 0.13-0.31 mg/kg, Pb 1.00-18.01 mg/kg, Co 0.25-2.90 mg/kg , Ni 3.75-5.93 mg/kg , Cr 3.83-5.32 mg/kg , Cu 1.01-1.90 mg/kg, Fe 23.65-30.10 mg/kg , Zn 13.70-25.63 mg/kg were observed in the bark of Tamarix aphylla. Thus it was concluded from the present study that the samples collected from polluted area were found more contaminated with heavy metals as compared to less polluted and nonpolluted area.
