Introduction: Sexual dimorphisms in biological structures such as brain and behaviour have been widely recognized in animals and humans. The purpose of this study was to examine whether there are sex differences in the size of the cerebellum with other body traits, such as the head, tail and brain. Methods: Twelve grasscutters comprising of 6 males and 6 females were used in this study. Each br...

OBJECTIVES To investigate deterioration of musculoskeletal system due to prolonged disuse and the potential of daily short-duration weight-bearing as countermeasures. METHODS Twenty-four adult male Sprague-Dawley rats were divided into Control Group (CG, no intervention), Tail-suspension Group (TG, tail-suspension without treatment), and Weight-Bearing Group (WBG, tail-suspension with 20 min/...

The evolution of the prehensile tail illustrates the impact habitat can have on structural traits. Prehensile primates are able to support their entire body weight using only their tail, which opens up new feeding opportunities in their arboreal environments. This trait evolved separately in two families of New World monkeys. A transitional behaviour in its proposed evolutionary mechanism is ta...

TAILTEST 9th call of the CS2 project started in 2019 year is aimed at development a multipurpose test rig for validation an innovative rotorcraft vertical tail. It conducted Czech Aerospace Research Centre (VZLU) as coordinator cooperating with Greek Athena centre (Athena RC) participant. The was initiated by Fokker Aerostructure Company and part chain contributing to conceptual aircraft type N...

Certain antenatal micronutrient supplements increased birth weight by 40-70 g in rural Nepal. The effect was estimated by calculating the mean difference in birth weight between control and treatment groups, which assumes a constant treatment effect across the birth weight distribution. By estimating differences (and CI) in birth weight between treatment and control groups as a nonlinear, smoot...

OBJECTIVE To evaluate association of blood lead levels with pregnancy outcome in the obstetrics and gynaecology unit. METHODS Blood lead levels were measured in 73 pregnant women at the time of delivery and assessed its association with pregnancy outcome. RESULTS Mean maternal lead level was 9.91+/-4.44 mg/dL (range 2.28-36.35 mg/dL). Mothers of boys had significantly higher (p=0.013, one-t...

Stem bark of Nyctanthes arbor-tristis Linn. was extracted in methanol to evaluate their analgesic and anti-inflammatory activities. The analgesic activity was determined on Wistar albino rats by hot plate method, tail flick assay, and tail immersion method using Morphine sulphate as standard drug at a dose of 5 mg/kg of body weight and the results were expressed as mean increase in latency afte...

High-impact exercise is considered to be very beneficial for bones. We investigated the ability of jump exercise to restore bone mass and structure after the deterioration induced by tail suspension in growing rats and made comparisons with treadmill running exercise. Five-week-old male Wistar rats (n = 28) were randomly assigned to four body weight-matched groups: a spontaneous recovery group ...

An allometric method for estimating the volume change in inflamed paw of rats is described. The technique is effective and advantageous for long term observation of adjuvant arthritis which lacks a suitable reference criterion due to the simultaneous swelling of the control paw. In the present method, the inflammatory intensity (IF) of paw edema is estimated by means of the formula; IF(%)=(2Vr/...

BACKGROUND Heparin and low molecular weight heparin are the most frequently used antithromboembolic drugs in fractures. OBJECTIVES We aimed to compare the effects of heparin and enoxaparin, which are used as standard treatment, on viability in degloving injuries. METHODS Thirty rats were used in the study. Three groups were composed including 10 rats in each group. Degloving injuries were f...
