Physical activity strengthens the musculoskeletal system, prevents commonly known problems such as backache and degenerative changes of the spine. Enhancing muscle strength reduces their load in daily activities. The increase of flexibility and agility along with balance decreases the risk of bone fractures and osteo-articular system [10]. One of the main causes of death in Poland are cardiovascular diseases. Physical activity is a relevant element of prevention of those diseases. The main aim of this study was  the evaluation of fats consumption in the diet of men training in FIT-MAX GYM club in Bydgoszcz. Additional aims were: determining motives for taking up and frequency of physical activity of the surveyed; the assessment of subjective evaluation of dieting and the knowledge of nutrition influence on the blood lipid profile. Result analysis and necessary calculations were done with use of the program Microsoft Excel. Data necessary for the study were gathered in FIT-MAX GYM club in Bydgoszcz among adult men. Anonymous questionnaire including 25 questions about the history of nutrition was held. Conclusions. 1. Men training at FIT-MAX GYM club in Bydgoszcz positively assessed their diet, especially when it comes to appropriate fat products consumption. 2. Physical activity was taken up by the respondents in order to improve their figure and mood. 3. Study group should be educated about the influence of dieting on blood lipid profile.
体育活动可以增强肌肉骨骼系统,防止常见的问题,如背痛和脊柱退行性变化。增强肌肉力量可以减少日常活动中的负荷。灵活性和敏捷性的提高以及平衡性的提高降低了骨折和骨关节系统的风险[10]。在波兰,造成死亡的主要原因之一是心血管疾病。体育活动是预防这些疾病的一个相关因素。本研究的主要目的是评估在比得哥什FIT-MAX健身俱乐部训练的男性饮食中的脂肪消耗。其他目的是:确定被调查者从事体育活动的动机和频率;主观评价节食和营养知识对血脂的影响。利用Microsoft Excel软件对结果进行了分析和必要的计算。研究所需的数据是在比得哥什的FIT-MAX健身俱乐部收集的。进行了包括25个关于营养史的匿名问卷调查。结论:1。在比得哥什FIT-MAX健身俱乐部训练的男性积极评估他们的饮食,特别是当涉及到适当的脂肪产品消耗时。2. 受访者进行体育锻炼是为了改善身材和情绪。3.应告知研究组节食对血脂的影响。

The biological interactions of the microflora in the human body are essential to maintain the somatic eco-physiological balance. Antibiotics, which are considered as a panacea against pathogens without knowing how it influences the microflora, could create a disease by disturbing the microbial ecosystem of the human body and develop new generations of antibiotics resistant pathogens. Medicinal plants could get rid the pathogens and also maintain the normal flora. There is a necessity to preserve the micoflora ecosystem, by means different approaches such as support the antibiotic treatment with some renovated compounds like natural medicinal compounds or probiotics, more comprehensive studies in this issue are badly needed.
人体内微生物群的生物相互作用是维持人体生理生态平衡的必要条件。在不知道抗生素如何影响微生物群的情况下,被认为是对抗病原体的灵丹妙药的抗生素,有可能扰乱人体的微生物生态系统,从而引发疾病,并产生新一代的耐抗生素病原体。药用植物既能清除病原菌,又能维持正常菌群。保护微生物生态系统是必要的,通过不同的方法,如用一些天然药物化合物或益生菌等更新的化合物来支持抗生素治疗,迫切需要对此问题进行更全面的研究。

Background: In the present research study, the rate of cutaneous wound healing and contraction rate in healthy rabbits using Aloe vera pulp was studied. Methods: Ten healthy rabbits were used for the study. They were divided into two groups consisting of five rabbits each. Cutaneous wounds were made on the lumbar region of each rabbit using a template which ensured that the wounds were of the same size in all the rabbits. 5ml of Aloe vera gel was applied to the wounds of the animals in the test group, while nothing was applied to the wound area of the animals in the control group. The wound area in each group was measured for a period of 21 days, using a venire caliper and tracing paper which was used to trace the wound area. Tissue samples were removed from the wound area in both experimental and control groups and subjected to routine histological analysis, also, morphometric analysis was performed. Results: The rate of wound contraction and mean centripetal contraction was calculated in both groups and graphically represented using Microsoft Excel. The results showed that animals who were treated with Aloe vera gel had a greater wound contraction rate, as well as rapid wound closure. The micrographs showed a thicker epithelial layer, with thinner collagen fibers in the dermis of experimental animals compared to the control group. There was also an abundant capillary bed at the dermal-epidermal junction in the experimental group, compared to the control group. Conclusion: Aloe vera may increase the rate of wound healing by accelerating epithelial migration, and may also play a role in neo-vascularization of the newly healed area. Keywords: Aloe vera, Cutaneous Wounds, Rabbits, Wound Contraction, Wound Healing
背景:本研究对健康家兔使用芦荟浆后皮肤创面的愈合率和收缩率进行了研究。方法:健康家兔10只。他们被分成两组,每组5只兔子。使用模板在每只兔的腰椎部位制作皮肤伤口,以确保所有兔的伤口大小相同。实验组动物创面涂芦荟凝胶5ml,对照组动物创面不涂芦荟凝胶。采用静脉卡尺和描画纸对创面进行描画,测量各组创面面积,为期21 d。实验组和对照组均取创面组织标本,进行常规组织学分析和形态计量学分析。结果:计算两组创面收缩率和平均向心收缩率,并用Microsoft Excel图形化表示。结果表明,用芦荟凝胶治疗的动物伤口收缩速度更快,伤口愈合速度也更快。显微照片显示,与对照组相比,实验动物真皮上皮层变厚,胶原纤维变薄。实验组与对照组相比,真皮与表皮交界处毛细血管床丰富。结论:芦荟可能通过促进上皮细胞的迁移而加快创面愈合速度,并可能在创面新血管形成中起作用。关键词:芦荟,皮肤伤口,家兔,伤口收缩,伤口愈合

Background: The identification of the reference values of certain serum biochemical parameters in relation to the age was studied in dromedary camels. Methods: Fourteen healthy young camels (age: 3-5 months), 12 adult male and 10 female camels (age: 5-8 years) were used. Venous blood samples were collected for the determination of certain serum parameters. Results: The reference range ( ± s×1.96) of serum- [Na + ] was 142-160 mmol/l and the percentile range (median (1. - 3.Quartile)) was 143-156 mmol/l for all age groups. The reference values of serum- [K + ] showed a significant (P<0.05) variation between the age groups being higher the young camels (4.2-7.4 mmol/l) compared to the adult groups (3.7-5.5 mmol/l). Serum- [Protein] and serum- [Albumin] showed significant (P<0.05) differences between the age groups. Significantly higher (P<0.05) reference range of 51-74 g/l and a percentile range of 59-67.7 g/l was observed in the adult female camels compared to young and adult male groups. Conclusion: These reference values are useful in detecting the influence of strong electrolytes such as Na + , K + and Cl - and weak acids (proteins) on the physiological and pathological status of the camels in relation to their age. Keywords: Camels, age, electrolyte concentrations, total protein, albumin, reference values.

Background: The objectives of this work are to study the physicochemical properties of tamarind fruit pulp for production of vinegar and to evaluate the quality characteristics of the produced vinegar. Methods: Two samples of tamarind were used in this study, sample A from Eastern Sudan and B from Western Sudan. They were analyzed for their physical, chemical composition and minerals content. Results: The acidity (%), total soluble solid, TSS Brix and pH values of tamarinds fruit pulp showed that sample A scored the higher value 28.87%, 42.2 Brix in acidity and TSS, respectively. All proximate analysis parameters determined were significantly different (P≤ 0.05) in the two samples except the ash content. Results showed that tamarind samples contain high amounts of Ca (149.13 – 174.19 mg/100g), in addition to Fe (68.94 – 80.67 mg/100g). The P content of the two samples was very low (3.63 – 9.06 mg/100g). For vinegar production, the fruit pulp was first digested and fermented with Saccharomyces cerevisae , and then acidified with Acetobacteraceti. No significant difference (P ≥0.05) was observed between samples A and B in refractive index, density (g/cm3) and pH between the two samples. After acidification step, the same properties were also estimated, the result were 1.35, 0.95(g/cm3) and 2.05, respectively for sample A, and 1.34, 0.94(g/cm3), 2.18 for, respectively for sample B. Sample B had the higher concentration vinegar (18.14%) compared to sample A (17.18%). Conclusion: tamarind fruit pulp could be recommended for vinegar production. Keywords: Tamarind, Physicochemical properties, Minerals, Vinegar quality .
背景:研究罗望子果肉制备食醋的理化性质,并对所制食醋的品质进行评价。方法:采用来自苏丹东部的罗望子A和来自苏丹西部的罗望子B作为研究样本。分析了它们的物理、化学成分和矿物质含量。结果:罗望子果肉的酸度(%)、总可溶性固形物(TSS)白利度(Brix)和pH值均以A样品较高,分别为28.87%、42.2白利度(TSS)。除灰分含量外,两种样品的近似分析参数均有显著差异(P≤0.05)。结果表明,罗望子样品中含有较高的钙(149.13 ~ 174.19 mg/100g)和铁(68.94 ~ 80.67 mg/100g)。两种样品的P含量都很低(3.63 ~ 9.06 mg/100g)。为了生产醋,首先用酿酒酵母消化和发酵果肉,然后用醋酸杆菌酸化果肉。A、B样品的折射率、密度(g/cm3)、pH值无显著性差异(P≥0.05)。经过酸化步骤后,也进行了相同的性能估计,样品A的结果分别为1.35、0.95(g/cm3)和2.05,样品B的结果分别为1.34、0.94(g/cm3)和2.18。样品B的醋浓度(18.14%)高于样品A(17.18%)。结论:罗望子果肉可推荐用于醋的生产。关键词:罗望子;理化性质;矿物质;

Abstract Background: Body Mass Index (BMI) which is often calculated by dividing the weight (kg) by height squared (m 2 ), was chosen as a simple measurement of body weight in relation to height. Waist circumference (WC) and Waist-hip-ratio (WHR) are important indices to assess abdominal obesity. Waist circumference (WC) is an expedient and easy measurement of intra-abdominal fat mass and total body bulk. Methods: This cross-sectional study was conducted on 130 undergraduate students of University of Maiduguri (comprising of 65 male students and 65 female students), with their ages ranging from 18-30 years. A written or verbal consent was obtained from the subjects after explaining to them the objectives as well as the methodology of the study.  Information about age and socioeconomic status was collected from each student in a pre-designed questionnaire. The height, weight, waist circumference, hip circumference were also taken on each individual using standard anthropometric methodology. Results: The prevalence of abdominal obesity in the present study, according to waist circumference (WC), and waist-hip-ratio (WHR) was 24.6% and 67.7% in males respectively, while 66.2% and 92.3% in female students respectively. Conclusion: The females in the same age group as males showed a tendency towards higher BMI and were classified as overweight and this could be attributed to reduced physical exercise and diet compared to their male counterparts. Keywords: body mass index, hip circumference, obesity, waist circumference, waist-hip ratio
摘要背景:体重指数(BMI)通常是用体重(kg)除以身高的平方(m2)来计算的,它是衡量体重与身高关系的简单指标。腰围(WC)和腰臀比(WHR)是评价腹部肥胖的重要指标。腰围(WC)是一种方便易行的腹部脂肪量和全身体积的测量方法。方法:对迈杜古里大学130名本科生(男65名,女65名)进行横断面研究,年龄在18-30岁之间。在向受试者解释研究目的和研究方法后,获得受试者的书面或口头同意。在预先设计的问卷中收集了每个学生的年龄和社会经济地位信息。身高、体重、腰围、臀围也采用标准人体测量方法测量。结果:以腰围(WC)和腰臀比(WHR)衡量,本组男生腹型肥胖患病率分别为24.6%和67.7%,女生腹型肥胖患病率分别为66.2%和92.3%。结论:与男性同龄的女性表现出更高的身体质量指数的趋势,并被归类为超重,这可能是由于与男性相比,她们的体育锻炼和饮食减少。关键词:体重指数,臀围,肥胖,腰围,腰臀比

Background: On-the-job Training is one of the most useful and economical methods for nurses to keep up with the latest progress in technology, as well as medical and social sciences. Encouraging nurses to improve their knowledge and skills is one of the most important responsibilities of a nursing management. This study aims to evaluate the effective factors in Motivating Nurses to Attend On-the-job Training Courses. Methods: This is a descriptive-analytical study which is on the basis of existing facts and information about the subject of the study. Our population comprises of 147 qualified nurses working in the hospitals of Torbat Heidariye University of Medical Sciences. Data was collected using questionnaire and analyzed using SPSS 21. Results: 46.3% of nurses were in 30-40 age group, 54.2% were females, 81.2% were married, 86.4% had B.S. 58.6% of nurses have been working in the hospital for less than 5 years. 87.8% of nurses were working on shifts, and the rest (1.8%) were supervisors. 94% of nurses agreed on the necessity of on-the-job training (moderately or highly required). Conclusion: we found out that there is no significant relationship between motivating factors and demographic characteristics. Also, there is an important difference between genders and organizational motivating factors. It means that the rate of male nurses’ participation in on-the-job training courses is higher than that of female nurses. Keywords: motivation, nurse, on-the-job training, hospital

Background. Assistive technology (AT) is regarded as one of the most important factors influencing functional recovery and independence in patients after stroke. There is still a need for research on predictors and early identification of AT requirements in order to shape and maximize its positive influence on the recovery process. Objective. To identify and evaluate relationship between selected factors (age, sex, time after cerebrovascular accident) and AT use. Results. Among 140 patients involved in the study, the use of AT was as follows: the most common AT equipment were wheelchairs (used by 40.81% of patients), canes (15.71%) and husks (15%). Up to 5 % patients used more than one AT device. Sex, age, time after cerebrovascular accident, and post-stroke complications were important factors influencing AT use in stroke-survivors. Conclusions. Study outcomes confirm important clinical information extending existing studies, especially co-occurrence of AT devices use.

Stem Cell Therapy for Male Infertility: A Review 干细胞治疗男性不育症:综述
Pub Date : 2016-07-11 DOI: 10.20286/NOVA-JMBS-050204
N. Dibal, M. Chiroma, M. Attah
Infertility affects 15% of couples in reproductive age world-wide and male factor is solely responsible in about 50% of the cases and contributory in 30-40% of cases. Spermatogonial stem cells (SSCs) are small self-renewing cells found in the basal compartment of seminiferous tubules where they form the foundation of spermatogenesis and are required for the continuous production of sperm. Transplantation of spermatogonial stem cells results in a donor derived sperm production and fertility in rodent and non-rodent species like Goat. Transplantation of cryopreserved spermatogonial stem cells could help oncology patients undergoing radiotherapy or chemotherapy by prior isolation of the SSCs and transplantation after treatment. Induced pluripotent stem cells also have the ability to differentiate into late stage germ cells. The efficacy and safety of SSCs transplantation showed that offspring produced did not show any morphological differences or alteration of genetic material but is most effective through assisted reproduction and better on young/immature Animals. The transfer of germ cells through micro-injection of seminiferous tubules and cannulation of efferent ducts is most effective on rodent testis while injection into the rete testis guided by ultrasound was reported to be the best technique in higher Animals (Bulls and Apes). Researches are still ongoing to get a safe and successful method of SSCs transplantation with no or less side effects on humans. Keywords: Cryopreserved, Pluripotent, self-renewing, Spermatogonia, and Spermatogenesis
全世界15%的育龄夫妇患有不育症,男性因素在约50%的病例中是唯一原因,在30-40%的病例中起作用。精原干细胞(ssc)是一种小的自我更新细胞,存在于精小管的基底室中,它们是精子发生的基础,也是精子持续产生所必需的。在啮齿类动物和山羊等非啮齿类动物中,精原干细胞移植可产生供体来源的精子和生育能力。冷冻保存的精原干细胞移植可以通过事先分离ssc并在治疗后移植来帮助接受放疗或化疗的肿瘤患者。诱导多能干细胞也具有向晚期生殖细胞分化的能力。ssc移植的有效性和安全性表明,所产生的后代没有表现出任何形态差异或遗传物质的改变,但通过辅助繁殖最有效,并且在幼龄/未成熟动物上效果更好。在啮齿类动物的睾丸中,通过精管微注射和传出管插管进行生殖细胞转移是最有效的,而在高等动物(公牛和猿类)中,超声引导下的睾丸输精管注射是最好的技术。寻找一种安全、成功、对人体无或少副作用的SSCs移植方法仍在研究中。关键词:冷冻保存,多能性,自我更新,精原细胞,精子发生
