  • According to Ayurveda, an individual can be classified into any one of the seven constitutional types (Prakriti) depending on the dominance of one, two, or three Doshas. A 'Dosha' is representative of fundamental mechanisms that are responsible for homeostasis, and thus, to health. In the recent years, there have been several efforts to see whether certain physiological, haematological or biochemical parameters have any relationship with the constitutional types or not. The objective of the present study was to see if the results of autonomic function tests vary according to Prakriti of an individual. We conducted this study in clinically healthy volunteers of both the gender belonging to the age group of 17 to 35 years after obtaining their written consent. The Prakriti of these volunteers was assessed on the basis of a validated questionnaire and also by traditional method of interviewing. After confirming that the primary Dosha ascertained by both these methods matched, 106 volunteers were grouped into three on the basis of primary Dosha and were subjected to various autonomic function tests such as cold pressor test, standing-to-lying ratio, Valsalva ratio and pupillary responses such as pupil cycle time and pupil size measurement in light and dark. The results suggest that, the autonomic function tests in the healthy individuals may correlate linearly with the primary Dosha expressed in an individual. In particular, people with Kapha as the most dominant Dosha showed a tendency to have either a higher parasympathetic activity or a lower sympathetic activity with respect to their cardiovascular reactivity in comparison to the individuals with Pitta or Vata as the most dominant Dosha.

  • Innate immune responses are primary, relatively limited, and specific responses to numerous pathogens and toxic molecules. Protein expression involved in these innate responses must be tightly regulated at both transcriptional level and post-transcriptional level to avoid the development of excessive inflammation that can be potentially harmful to the host. MicroRNAs are small noncoding RNAs (∼22 nucleotides [nts]) that participate in the regulation of numerous physiological responses by targeting specific messenger RNAs to suppress their translation. Recent work has shown that several negative regulators of transcription including microRNAs play important roles in inhibiting the exacerbation of inflammatory responses and in the maintenance of immunological homeostasis. This emerging research area will provide new insights on how microRNAs regulate innate immune signaling. It might show that dysregulation of microRNA synthesis is associated with the pathogenesis of inflammatory and infectious diseases. In this review, we focused on miR-146 and miR-125 and described the roles these miRNAs in modulating innate immune signaling. These microRNAs can control inflammatory responses and the outcomes of pathogenic infections.

  • The purpose of this study was to evaluate the effect of wearing induced micro current brassiere on the physiological responses of women. Four women participated to wear a different brassiere condition: with and without micro current chips. Subjects were carried out after wearing the induced micro current brassiere for 120minutes. Eardrum temperature, skin temperature, blood pressure, heart rate, thermal perception, humid perception, and comfort perception were obtained. The results were as follows. The brassiere with micro current chips showed better performance on weight loss than the brassiere without micro current chips. Participants in a higher level of BMI were more likely to lose greater weight. Mean skin temperatures decreased with micro current chips. Participants felt more comfortable for walking in micro current brassiere than in brassiere without micro current chips.

  • Maintaining internal homeostasis and regulating innate behaviors are essential for animal survival. In various animal species, a highly conserved neuroendocrine system integrates sensory inputs and regulates physiological responses to environmental and internal changes. Diuretic hormones 44 and 31, which are homologs of mammalian corticotropin-releasing factor (CRF) and calcitonin gene-related peptide (CGRP), respectively, control body fluid secretion in Drosophila. These neuropeptides and their receptors have multiple physiological roles, including the regulation of body-fluid secretion, sleep:wake cycle, internal nutrient-sensing, and CO2-dependent response. This review discusses the physiological and behavioral roles of DH44 and DH31 signaling pathways, consisting of neuroendocrine cells that secrete DH44 or DH31 peptides and their receptor-expressing organs. Further research is needed to understand the regulatory mechanisms of the behavioral processes mediated by these neuroendocrine systems.

  • In this study we tried to examine the efficiency of the agricultural convenient tool (put-on-style-stool) by observing subjects'physiological responses. For this we measured subjects' heart rate, oxygen consumption, blood lactate level, mean skin temperature and rectal temperature. The results of this study are as follows; Heart rate was 75$\pm$2 beats/min with the put-on-style-stool and 78$\pm$2 beats/min without it (P<0.01). Oxygen consumption was 3.88$\pm$1.90 $m\ell$/kg/min with the Put-on-style-stool and 5. 06$\pm$0.40 $m\ell$/kg/min without it (P<0.05). Blood lactate level was 2.39$\pm$0.64 mmol with the put-on-style-stool and 3.38$\pm$0.45 mmol without it (P<0.05). Mean skin temperature was lower but rectal temperature was higher with than without the put- on - style - stool (P<0.05 and P<0.01 respectively) So, using the put-on-style-stool was evaluated positively in farmer's work.
