The aim of our study was to evaluate the morphogenetic variability as a marker of smoking dependency in adult smokers versus controls and to investigate the presence and the degree of morphogenetic variability difference between male and female smokers versus same gender controls. The cross-sectional study evaluated 241 smokers and 185 nonsmoker individuals as controls. We analyzed 17 homozygous recessive characteristics (HRC). There was a significant difference in the individual variations of 17 HRCs between the controls and smokers (??2=61.400, p<0.001; for females ??2=79.440, p<0.001; for males ??2=84.972, p<0.001). The mean values of HRCs significantly differed between smokers and controls (MV?SEM(Controls) -4.79?0.13, MV?SEM(Smokers) -5.70?0.12; p<0.001). For males, presence of 6/17 (35.29% genetic homozygosity) HRCs (OR=6.12) was to the certain degree predictor for smoking dependency. Higher degree of genetic homozygosity, changed variability and male gender, might be some among potential numerous factors that could have impact on smoking development and dependence.

Background and aim: Car crashes are among the prevalent incidents seriously threatening public health. This study aimed to assess the survival and quality of hospital care for patients of car accidents in Western Azerbaijan, Iran. Methods: This cross-sectional study was conducted on 1,697 trauma victims admitted to Imam Khomeini hospital in Urmia, Iran, during 2016. The data, including systolic pressure, Glasgow Coma Scale, respiratory rate prior to admittance, severity of injuries based on surgery description, limbs and brain computed tomography scan, and diagnostic ultrasound by an specialist, were collected from medical records. The survival chance of patients was estimated using Trauma and Injury Severity Score (TRISS). To evaluate the quality of hospital service, Z and W statistics were utilized. Results: Out of 1,697 admitted victims, 1,226 (72.3%) and 471 (27.7%) subjects were male and female, respectively. The patients were within the age range of 15-54 years, including 901 (75%) male and 296 (25%) female subjects. The predominant educational levels were under diploma and illiterate in male and female patients, respectively. The mean values of the Revised Trauma Score for the recovered and deceased patients were 7.75±0.38 and 6.19±1.59, respectively; however, the mean values of the Injury Severity Score for the recovered and deceased patients were 14.57±13.72 and 52.03±27.02, respectively, indicating a statistically significant difference between the two groups. The number of observed mortalities was 69; nevertheless, the expected mortalities were 60 cases. Furthermore, the quantified W and Z statistics were -9 and 0.02, respectively. Conclusions: The results showed that the observed mortality exceeded the expected morality indicating the low quality of hospital care.

ABSTRACT Gonadotrophic activity was estimated in individual plasma samples of 46 male and female subjects of all ages. The plasma was extracted by means of an ammonium acetate-ethanol procedure and tested biologically by the mouse uterine weight assay. The values in postmenopausal plasma ranged from 10 to 46 milligram-equivalents of the 2nd International Reference Preparation for Human Menopausal Gonadotrophin per litre. Plasma of men and women in the reproductive years contained 0.6–3.0 and 0.5–2.4 milligram-equivalents of the 2nd IRP per litre. The results in female plasma were assembled according to the day of the menstrual cycle. Though there was no significant difference in the mean values between group A (days 1–9), B (days 10–19) and C (days 20–30), the highest value was observed on the 13th day of the cycle of a 37 years old woman.

Objectives: Thoracic outlet syndrome (TOS) is an upper extremity disorder resulting from compression of brachial plexus structures and subclavian vessels within thoracic outlet region at any of the three primary sites- interscalene triangle, costoclavicular space and retro-pectoralis minor space. This study focused on detailed anatomic exploration and measurement of normal anatomic variability within interscalene triangle and costoclavicular space. Material and Method:  We examined 49 cadavers (22 male and 27 female) and dissected both sides to explore and examine 98 dissected areas. We measured the base width, height, angle within interscalene triangle and the vertical distance within costoclavicular space. We also calculated the area of interscalene triangle. Results: The mean values of base width, height, interscalene angulation of interscalene triangle and height of costoclavular space was 10.18±4.31 mm, 45.19±0.07mm, 10.85±0.06 degrees and 10.22±0.07 mm respectively. The mean area of interscalene triangle was 214.82±5.22sqmm. Conclusion: We have found clinically significant differences between the interscalene and costiclavicular space vertical heights; the height of costoclavicular space was clinically significantly lower than the interscalene space (p< 0.001). No clinical significant difference was found between male and female measurements. These ranges of dataset could be useful for planning treatment approaches in TOS.

Study of Seven heavy metals namely, Zinc, Lead, Copper, Cadmium, Manganese, Chromium and Nickel was conducted in Mai-Allo pond, Gwale, Kano State in order to assess the concentration of the heavy metals in the pond. The results of the heavy metals showed that Zn has a value of 0.34±0.17 mg-l in the wet season and 0.49±0.37 mg-l in the dry season, Cu has a value of 1.42±0.14 mg-l in the wet season and 0.64±0.09 mg-l in the dry season, and Ni also has 0.12±0.02 mg-l in the wet season and 0.23±0.13 mg-l in the dry season, all these were within acceptable limits, while Pb with a value of 0.05±0.02 mg-l was within the limits during the wet season but during the dry season, the value 0.14±0.09mg-l exceeds the limits. Cd has a value of 0.06±0.01 in the wet season and 0.17±0.12 in the dry season, Cr has 0.36±0.12 in the wet season and 0.04±0.07 in the dry season, and Mn also has values of 0.46±0.12 and 0.22±0.03 in the wet and dry seasons respectively. Hence there was no significant difference (P>0.05) in the mean values of the sampling stations of the heavy metals during the wet and dry seasons. The study showed that the pond water was polluted with some heavy metals and hence measures must be taken to ensure the safety of the aquatic ecosystem, humans and the environment.

ABSTRACT A comparison has been made between (A), a relatively simple method for the measurement of aldosterone secretion rate, based on paper chromatography and direct densitometry of the aldosterone spot and (B) a more elaborate isotope derivative method. The mean secretion rate in 9 normal subjects was 112 ± 26 μg per 24 hours (method A) and 135 ± 35 μg per 24 hours (method B). The »secretion rate« in one adrenalectomized subject after the intravenous injection of 250 μg of aldosterone was 230 μg per 24 hours (method A) and 294 μg per 24 hours (method B). There was no significant difference in the mean values, and correlation between the two methods was good (r = 0.80). It is concluded that the densitometric method is suitable for clinical purposes as well as research, being more rapid and less expensive than the isotope derivative method. Method A also measures the urinary excretion of the aldosterone 3-oxo-conjugate, which is of interest in many pathological conditions. The densitometric method is obviously the less sensitive and a prerequisite for its use is an aldosterone secretion of 20—30 μg per 24 hours. Lower values are, however, rare in adults.
