activities (simulated combat situation). The results showed a percentage of muscle tissue of 45.4 – 2.9 % (95%CI: 44.6 - 46.2), while the percentage of adipose tissue was 20.3 – 4.9 % (95%CI). : 14.7-17.3). Negative correlations of small magnitude were found between race time (5000 m) and muscle tissue (%) (r = -0.275) and positive with adipose tissue (%) (r = 0.294). However, high magnitude correlations were observed between pull-ups and muscle tissue (%) (r = 0.517) and adipose tissue (%) (r = -0.558). Adipose tissue was negatively related to aerobic capacity, upper body endurance strength and abdominal endurance strength, while muscle tissue was positively related to these same variables. No correlations were found between body composition and military operational capacity (p<0.05). It is concluded that body composition and physical condition are not related to military operational capacity in combat situations in infantry specialists, but body composition is related to strength and cardiorespiratory capacity.

In solid and malignant tumors, innate and adaptive immunity are combined in antitumor responses. This study aimed to analyze the activation of plasma cells and the correlation between the infiltration of B and T lymphocytes with the degree of malignancy or Gleason grade in human prostate biopsies diagnosed with cancer. Prostate cancer biopsies were obtained from the Clinical Hospital of Universidad de Chile (n=70), according to the bioethical norms of the institution. Histological sections of 5µm thickness were processed for immunohistochemistry with primary antibodies against BL and total TL (HRP/DAB). Recognition and quantification were performed under a Leica DM750 optical microscope. Microsoft Excel and GraphPad software were used for the statistical study. Correlation coefficient (Pearson) and mean comparison tests (Kruskal-Wallis and Dunn) and p⤠0.05 were developed. B and T lymphocyte populations were inversely interregulated in prostate cancer (Gleason) (r= -0.46). Their relationship with Gleason grade is variable according to lymphocyte type (LB vs. Gleason r= -0.0.47 and LT vs. Gleason r= -0.21). Histological diagnosis of prostate cancer correlates with a predominance of LT. The malignancy of the pathology correlates with a predominance of LTs, according to the Gleason grade. The increased knowledge of B and T lymphocyte infiltration and plasma cell activation could be used to better target clinical trials on treatments based on immune system responses. Immunotherapy could be a new paradigm to apply better antitumor therapy strategies.
在实体瘤和恶性肿瘤中，先天免疫和适应性免疫结合在抗肿瘤反应中。本研究旨在分析诊断为癌症的人前列腺活检中浆细胞的活化以及B淋巴细胞和T淋巴细胞浸润与恶性程度或Gleason分级的相关性。根据智利大学临床医院的生物伦理规范，在该医院进行了前列腺癌活检(n=70)。用抗BL和总TL (HRP/DAB)的一抗对5µm厚度的组织切片进行免疫组织化学处理。在徕卡DM750光学显微镜下进行识别和定量。采用Microsoft Excel和GraphPad软件进行统计研究。进行相关系数检验(Pearson)、均数比较检验(Kruskal-Wallis和Dunn)和p¤0.05检验。B和T淋巴细胞群在前列腺癌中呈负互调节(Gleason) (r= -0.46)。其与Gleason分级的关系因淋巴细胞类型不同而不同(LB vs. Gleason r= -0.0.47, LT vs. Gleason r= -0.21)。前列腺癌的组织学诊断与lt的优势相关。根据Gleason分级，病理的恶性与lt的优势相关。对B淋巴细胞和T淋巴细胞浸润和浆细胞活化的认识的增加可用于更好地靶向基于免疫系统反应的治疗的临床试验。免疫治疗可能是应用更好的抗肿瘤治疗策略的新范例。

The study will provide information on the morphometrics of the vertebrae, which can be used to guide clinicians on the appropriate size of transpedicular screws to use in spine interventions among the Jordanian population and for comparative studies with other races. A retrospective analysis of normal CT scans of the lumbar and thoracolumbar areas was done. Linear and angular measurements of 336 vertebrae were collected for 25 males and 23 females. The results were compared between right and left and between both sexes. The L5 has the longest AVBH and the shortest PVBH in both sexes, it also, had the shortest and widest pedicle in both males and females. ratio of the AVBH to PVBH showed progressive increase in both sexes from T11 to L5. Similarly, the VBW increased progressively from the top to the bottom in both sexes, but it was significantly different between both sexes. The L1 was the most cranially oriented vertebrae in males while the L2 showed the most cranial orientation in females. Both sexes L5 was the most caudally oriented vertebrae. This study provides a database for vertebral morphometrics in the Jordanian population, there are slight differences between the right and left side in the upper studied vertebrae (T11-L2) and some measurement showed significant differences between males and females. These findings need to be taken into consideration when inserting pedicle screws.
