Habiba Rashid, Touqeer Ahmed
Stress induces retrograde amnesia in humans and rodents. Muscarinic antagonism under normal physiological conditions causes gender dependent impairment in episodic memory retrieval. We aimed to explore the gender dependent role of muscarinic receptors in memory retrieval under sub-chronic stress condition. Male and female mice were trained for Morris water maze test and contextual fear conditioning, followed by 3 hour restraint stress per day for five days. Stress was either given alone or in combination with a daily subcutaneous injection of scopolamine (1 mg/kg) or donepezil (1 mg/kg)...

The urotoxicity is a common complication associated with patients receiving cyclophosphamide (CYP). This study was designed to investigate the uroprotective mechanism of quercetin (Quer) flavonoid against CYP induced urotoxicity via determination of oxidative stress markers as well as inflammatory mediators in bladder tissue. Forty male Wistar rats were divided into four groups; Normal group: received saline for 10 days. Quer control group: received quercetin 50 mg/kg/day for 10 days. CYP group: received saline for 10 days and injected with a single dose of 150 mg/kg CYP intraperitoneal (i...

Objective To analyze the therapeutic effect of green tea polyphenols (GTP) in mice with colitis induced by TNBS and its possible mechanism. Methods Colitis was induced by TNBS in BALB/C mice. The mice were randomly divided into GTP group (n=10) and TNBS model group (n=10). Mice in the GTP group were given GTP [0.2 mL at a dose level of 100 mg/(kg.d)] by oral gavage, and mice in the model group were given normal saline [0.2 ml/d] by gavage. Four weeks later, the mice were sacrificed. Disease activity index (DAI) and inflammatory score were evaluated by HE staining...

BACKGROUND: Dexmedetomidine has been shown to have an analgesic effect. However, no consensus was reached in previous studies. METHODS: Electronic databases such as PubMed, Embase, and Cochrane Central were searched for relevant randomized controlled trials (RCTs). The relative risk (RR) and weighted mean difference (WMD) were used to analyze the outcomes. Random-effects model was used for meta-analysis. RESULTS: Compared to the normal saline group, patients using dexmedetomidine showed a significantly decreased pain intensity within 6 hours (WMD=-0...

Whether alveolar liquid surface tension, T, is elevated in the acute respiratory distress syndrome (ARDS) has not been demonstrated in situ in the lungs. Neither is it known how exogenous surfactant, which has failed to treat ARDS, affects in situ T. We aim to determine T in an acid-aspiration ARDS model before and after exogenous surfactant administration. In isolated rat lungs, we combine servo-nulling pressure measurement and confocal microscopy to determine alveolar liquid T according to the Laplace relation...

The umbilical cord and placental have been considered to significantly contribute to the perinatal outcome. Long or short cord can lead to intrauterine fetal demise. So this type of study in placenta and umbilical cord can yield information for immediate and later management of newborn. This information may also be essential for protecting the attending physician in the event of a fetal outcome. This Cross sectional descriptive study would provide information about the length of umbilical cord in different gestational age groups in Bangladesh...

We examined the effect of treatment with neostigmine alone or with atropine on brain oxidative stress and on brain and liver tissue damage following acute malathion toxicity. Rats were intraperitoneally treated with malathion 150 mg/kg along with neostigmine (200 or 400 μg/kg) or neostigmine (200 μg/kg) + atropine (1 mg/kg) and euthanized 4 h later. Results indicated that compared with the saline group, malathion resulted in (i) higher brain malondialdehyde (MDA) and nitric oxide (46.4% and 86.2%); (ii) decreased brain reduced glutathione (GSH) (67...

The aim of the present study was to investigate the influence of liposome‑plasmid encoding mutant survivin‑T34A (PST34A) on tumor growth in cervical cancer in vivo. Liposome‑plasmid DNA encoding mutant survivin‑T34A was constructed and administered via an intraperitoneal injection in mice inoculated with cervical cancer cells. Following the establishment of the tumor model, the animals were randomly divided into four groups: i) The normal saline group (NS; 100 µl sterile saline once/3 days for 15 days); ii) the 1,2‑dioleoyl‑3‑trimethylammonium‑propane (DOTAP) control (100 µg DOTAP once/3 days for 15 days); iii) the plasmid PST34A (10 µg PST34A once/3 days for 15 days); and iv) the PST34A+DOTAP (10 µg PST34A+100 µg DOTAP once/3 days for 15 days)...

Introduction: The effects of statins on lipoprotein-associated phospholipase A2 (Lp-PLA2) are controversial, and the present study aimed to investigate whether atorvastatin could reduce Lp-PLA2 in rats with dyslipidemia. Material and methods: A high-fat and high-cholesterol diet was prescribed to produce a dyslipidemia model. Thereafter, low-dose atorvastatin (5 mg/kg/day), high-dose atorvastatin (20 mg/kg/day) or saline (without-treatment group) was prescribed for 14 days...

BACKGROUND: Knee Osteoarthritis (KOA) is a very common condition with prevalence rising with age. It is a major contributor to global disability and has a large socioeconomic burden worldwide. Conservative therapies have marginal effectiveness, and surgery is reserved for severe symptomatic KOA. Dextrose Prolotherapy (DPT) is an evidence-based injection-based therapy for chronic musculoskeletal conditions including KOA. The standard "whole joint" injection method includes intra-articular injection and multiple extra-articular injections at soft tissue bony attachments...

n-Hexane is an organic solvent widely used in industry. 2,5-Hexanedione (2,5-HD), the major neurotoxic metabolite of n-hexane, decreases the levels of neurofilaments (NFs) in neurons. Neurogenesis occurs throughout life, and the hippocampal dentate gyrus is one of two major brain areas showing neurogenesis in adulthood. In the current study, rats were intraperitoneally injected with normal saline solution or 2,5-HD five times per week for five continuous weeks. 2,5-HD was administered to the low-dose and high-dose groups at 200 and 400 mg/kg/day, respectively...
