Purpose: To assess the growth hormone(GH) response to the Wingate anaerobic test(WAn T) among children with short stature and suspected GH deficiency. We hypothesized that the GH response to the WAn T would be similar to the GH response to a commonly used pharmacologic provocation ***: Ten children(6 males and 4 females, age range 9.0–14.9 years) participated in the study. Each participant performed 2 tests: a standard all-out WAn T, cycling for 30 s against constant resistance, and a standardized pharmacologic test(clonidine or glucagon). Blood samples for GH were collected before and 10, 30, 45, and 60 min after the beginning of exercise. In addition, we collected pre-and post-exercise blood lactate ***: There was a significant increase in GH levels after the WAn T, yet in 9 of 10 participants, this increase was below the threshold for GH sufficiency. Peak GH after the WAn T was significantly lower compared to the pharmacologic GH provocation tests(with 9 of 10 demonstrating GH-sufficient response).Conclusion: The traditional WAn T cannot be used as a GH provocation test. Further research is needed to develop anaerobic exercise protocols sufficient to promote GH secretion.

The aim of the study was to examine the effect of Newcomb ball (also known by the name of catchball) training on the physical fitness of women at midlife. One hundred and eighteen women, aged 29 - 45 yrs, were assigned to an experimental group (EG) or a control group (CG), and completed two similar sets of tests before and after seven months of training. The EG performed two Newcomb ball training sessions per week that included technical and tactical drills with and without the ball, small sided games and full games at different variations. The CG remained non-active throughout the seven months. Leg power, arm power, agility, speed, and aerobic scores were significantly higher for the EG compared to the CG at baseline (p p p < 0.05), were found for the CG in any of the other fitness variables. The findings indicate that amateur Newcomb ball training can be used as an efficient and enjoyable tool for fitness development among midlife women.

The climate crisis disproportionately impacts disabled people. Yet climate-related advocacy, planning, and policymaking often neglect to thoughtfully include disabled people. Responding to this gap, disabled and neurodivergent environmental activists coined the term eco-ableism to describe discrimination and silencing toward disabled and neurodivergent people (i.e., ableism) arising in environmental spaces (i.e., eco-ableism). Relatedly, building operations and construction practices contribute a significant percentage of global, energy-related CO_(2) emissions annually, which calls into question the relationships between the impending climate crisis, disability justice, and architecture. Climate-specific, natural building materials and methods present a potential pathway toward a more sustainable built future: low-carbon, locally sourced, minimally processed, and nontoxic materials. Despite a critical overlap, there is little published research on material access in the production phase and human access in the occupation phase of natural buildings. Applying eco-ableism and material circularity in an architectural framework, this research aims to investigate the gaps and possibilities of access, natural material applications, and resulting US natural buildings informed by scholarship in critical disability studies and semi-structured interviews with natural building professionals.

Methane dominated gas is one of the cleanest energy resources;however, there is no direct method to determine its source rock. Natural gases produced from the eastern Sichuan Basin together with seismic data were studied for their sources and secondary alteration by thermochemical sulfate reduction(TSR). Our results demonstrate that Upper Permian to Lower Triassic(P_(3)ch-T_(1)f) gases in the surrounding of the Kaijiang-Liangping area show volatile organic sulfur compounds(VOSCs) δ^(34)S values close to those of the associated H_(2)S, and may have been altered by methane-dominated TSR, resulting in positive shift in methane δ^(13)C_(1)values with increasing TSR extents. Other(or group 2) gases produced from the P_(3)ch-T_(1)f reservoirs from the southern area and the Upper Carboniferous to Middle Permian(C_(2)h-P_(2)q) from the eastern Sichuan Basin are not significantly changed by TSR, show similar δ^(34)S values between the kerogens and some VOSCs, and may have been derived from the Lower Silurian and Middle Permian source rocks. This study demonstrates a case for the first time showing the δ^(34)S values of VOSCs can be used as a tool for direct correlation between non-TSR altered gas and source rocks. Methane-dominated gas pools can be found using gas and source rock geochemistry combined with seismic data.

以甲烷为主的天然气是最清洁的能源资源之一,但是目前还没直接的方法用以确定其烃源岩.为此,本研究分析了川东地区天然气地球化学和地震资料,确定热化学硫酸盐还原(TSR)等次生过程对天然气的改造作用,并探讨了天然气的来源.研究结果表明,第一类天然气分布于开江-梁平地区周围上二叠统-下三叠统(P_(3)ch-T_(1)f),其挥发性有机硫化合物(VOSCs)δ^(34)S值与伴生H_(2)S相近,可能经历了以甲烷为主的TSR作用;随着TSR程度的增强,甲烷δ^(13)C_(1)值发生正偏移.第二类来自川东地区的下石炭统-中二叠统(C_(2)h-P_(2)q)以及南部地区的天然气,未受到明显的TSR影响,天然气中某些VOSCs与干酪根之间的δ^(34)S值相似,可能来自下志留统和中二叠统的烃源岩.本研究提出VOSCs的δ^(34)S值可作为非TSR改造天然气与烃源岩直接对比的指标.天然气和烃源岩地球化学数据与地震数据相结合,可以作为一种有效勘探天然气藏的方法.

AIM:To review and summerize the current literatue regarding M2A wireless capsule endoscopy. METHODS:Peer reviewed publications regarding the use of capsule endoscopy as well as our personal experience were reviewed. RESULTS:Review of the literature dearly showed that capsule endoscopy was superior to enteroscopy,small bowel follow through and computerized tomography in patients with obscure gastrointestinal bleeding,iron deficiency anemia, or suspected Crohn's *** was very sensitive for the diagnosis of small bowel tumors and for survailance of small bowel pathology in patients with Gardner syndrome or familial adenomatous polyposis *** role in celiac disease and in patients with known Crohn's disease was currently being investigated. CONCLUSION:Capsule video endoscopy is a superior and more sensitive diagnostic tool than barium follow through, enteroscopy and entero-CT in establishing the diagnosis of many small bowel pathologies.

Wireless capsule endoscope (WCE) for the investigation of the small bowel is an approved technique both in adults and children (more than 10 years old). The present review provides data on the indications, diagnostic yield, adverse events and limitations of the WCE technique in children and tries to predict the future of WCE usage in this population of patients.

Smoking is an important environmental factor in inflammatory bowel disease （IBD） with differing effects in ulcerative colitis （UC） and Crohn＇s disease （CD）. Never smoking and formerly smoking increase the risk of UC, whereas smoking exacerbates the course of CD. The potential mechanisms involved in this dual relationship are yet unknown. A reasonable assumption is that smoking has different effects on the small and large intestine. This assumption is based on animal and human studies that show that the effects of smoking/nicotine on CD and UC depend on the site of inflammation and not on the type of disease.
