Bile Acids Function and Their Interaction with Gut Bacteria

Bile acids (BAs) posses many important physiological roles. It has recently emerged that BAs are also signaling molecules with systemic endocrine functions. BAs are ligands for the G-protein-coupled receptor TGR5, and activate nuclear hormone receptors such as farnesoid X receptor α. Through activation of these diverse signaling pathways, BAs can regulate triglyceride, cholesterol, energy, and glucose homeostasis, and at the same time inhibit the overgrowth of gut bacteria. The mammal large intestine harbors a complex microbial flora and the interaction between BAs and gut bacteria is complex. Gut bacteria are very important for the biotransformation of BAs, furthermore, the intestinal micronota is very efficient in hydrolyzing conjugated endobiotics and xenobiotics, and this favors the reactivation and the enterohepatic circulation of compounds that have been eliminated through the bile. In contrast, the host suppresses significant bacterial colonization by a variety of mechanisms, including rapid transit times, antimicrobial peptides, proteolytic enzymes, and bile acids. Commensal and pathogenic microorganisms must resist the deleterious actions of bile in order to survive in the mammal gastrointestinal tract. This review focus on current advances in obesity controlling and inhibition of gut bacteria by bile acids,and the interaction between bile acids and gut bacteria.
A Computational Study of Executive Dysfunction in Amyotrophic Lateral Sclerosis

Executive dysfunction is a well-documented, yet nonspecific corollary of various neurological diseases and psychiatric disorders. Here, we applied computational modeling of latent cognition for executive control in amyotrophic lateral sclerosis (ALS) patients. We utilized a parallel reinforcement learning model of trial-by-trial Wisconsin Card Sorting Test (WCST) behavior. Eighteen ALS patients and 21 matched healthy control participants were assessed on a computerized variant of the WCST (cWCST). ALS patients showed latent cognitive symptoms, which can be characterized as bradyphrenia and haphazard responding. A comparison with results from a recent computational Parkinson’s disease (PD) study (Steinke et al., 2020, J Clin Med) suggests that bradyphrenia represents a disease-nonspecific latent cognitive symptom of ALS and PD patients alike. Haphazard responding seems to be a disease-specific latent cognitive symptom of ALS, whereas impaired stimulus-response learning seems to be a disease-specific latent cognitive symptom of PD. These data were obtained from the careful modeling of trial-by-trial behavior on the cWCST, and they suggest that computational cognitive neuropsychology provides nosologically specific indicators of latent facets of executive dysfunction in ALS (and PD) patients, which remain undiscoverable for traditional behavioral cognitive neuropsychology. We discuss implications for neuropsychological assessment, and we discuss opportunities for confirmatory computational brain imaging studies.
Long-term outcomes of upfront concurrent chemoradiotherapy followed by P-GDP regimen in newly diagnosed early stage extranodal nasal-type NK/T cell lymphoma

Abstract The optimal treatment strategy of newly diagnosed stage I/II, extranodal nasal-type natural killer/T cell lymphoma (NKTCL) remains unclear. This prospective phase II trial was conducted to explore the short-term and the long-term efficacy and safety of upfront concurrent chemoradiotherapy (CCRT) followed by pegaspargase, gemcitabine, dexamethasone, cisplatin (P-GDP) regimen in patients newly diagnosed with early stage NKTCL. Thirty patients newly diagnosed with stage I/II NKTCL were enrolled from January 2013 to December 2016, and treated as the following strategy: upfront CCRT with cisplatin weekly (25 mg/m2) for 5 weeks, followed by 3 cycles of P-GDP regimen chemotherapy (pegaspargase 2500IU/m2 capped at 3750IU, intramuscular on day 4, gemcitabine 850 mg/m2 intravenous on days 1 and 8; dexamethasone 40 mg/day intravenous on days 1 to 4; and cisplatin 20 mg/m2 intravenous on days 1–3) 3 weeks after the completion of CCRT. The objective response rate (ORR) and the complete response (CR) rate were the primary endpoints, and the secondary endpoints were the overall survival (OS), progression-free survival (PFS), and the adverse event (AE). The median follow-up period was 51.5 months (range, 5–78months). The ORR was 93.3% (28/30) and all these 28 patients attained CR at the end of the treatment. Two patients suffered from lymphoma associated hemophagocytic syndrome (LAHS) during the period of consolidation chemotherapy and died within 2 months. The 5-year OS was 93.3%, and the 5-year PFS was 89.4%Mucositis was the most common grades 3/4 nonhematologic AEs (10%, 3/30) of CCRT. During the P-GDP chemotherapy, vomiting (6.7%, 2/30), neutropenia (43.3%, 13/30) and thrombocytopenia (23.3%, 7/30) were the major grades 3/4 toxicities during chemotherapy. No treatment-related deaths occurred. The upfront CCRT followed by P-GDP regimen chemotherapy is an effective and well-tolerated first-line treatment strategy for patients diagnosed with early stage NKTCL. Further investigation of larger sample size is warranted.
Investigation of Correlated Internet and Smartphone Addiction in Adolescents: Copula Regression Analysis

Internet and smartphone addiction have become important social issues. Various studies have demonstrated their association with clinical and psychological factors, including depression, anxiety, aggression, anger expression, and behavioral inhibition, and behavioral activation systems. However, these two addictions are also highly correlated with each other, so the consideration of the relationship between internet and smartphone addiction can enhance the analysis. In this study, we considered the copula regression model to regress the bivariate addictions on clinical and psychological factors. Real data analysis with 555 students (age range: 14–15 years; males, N = 295; females, N = 265) from South Korean public middle schools is illustrated. By fitting the copula regression model, we investigated the dependency between internet and smartphone addiction and determined the risk factors associated with the two addictions. Furthermore, by comparing the model fits of the copula model with linear regression and generalized linear models, the best copula model was proposed in terms of goodness of fit. Our findings revealed that internet and smartphone addiction are not separate problems, and that associations between them should be considered. Psychological factors, such as anxiety, the behavioral inhibition system, and aggression were also significantly associated with both addictions, while ADHD symptoms were related to internet addiction only. We emphasize the need to establish policies on the prevention, management, and education of addiction.
What factors affect the methodological and reporting quality of clinical practice guidelines for osteoporosis? Protocol for a systematic review

Abstract Background: Osteoporosis is a disease with a high prevalence and low treatment rate, which poses a serious threat to the lives of patients and brings a heavy economic burden. Clinical practice guidelines (CPGs) provide vital guidance for disease management. Up to now, different countries, regions, and organizations have issued a certain number of CPGs for osteoporosis, but the recommendations in different guidelines are inconsistent. This protocol plans to evaluate the quality of the CPGs for osteoporosis and then make a comparative analysis of the recommendations in the CPGs. Methods: Several databases including PubMed, Web of Science, Embase, and Cochrane Library, as well as the official website of relevant organizations will be searched. Screen and data extraction will be performed by two reviewers independently, and the third reviewer help to resolve the divergence between them. Using the AGREE II instrument and RIGHT checklist to assess the methodological and reporting quality of the CPGs. The extracted recommendations, including but not limited to screening, diagnosis, evaluation and treatment, will be summarized and analyzed, and the results will be presented in tabular form. Bubble charts will be used to show quality differences between CPGs and to describe the correlation between methodological and reporting quality through regression analysis. Excel, EndnoteX9 and SPSS 25.0 will be used. Result: To evaluate the advantages and disadvantages of the existing CPGs of osteoporosis and analyze the similarities and differences between the recommendations, the results will be published in a peer-reviewed journal. Conclusion: This study will provide systematic evidence for existing CPGs of osteoporosis and to provide a reference for CPGs users. Protocol Registration: INPLASY 202070031.
Factors influencing productivity of eastern wild turkeys in northeastern South Dakota

Abstract Population growth is highly sensitive to changes in reproductive rates for many avian species. Understanding how reproductive rates are related to environmental conditions can give managers insight into factors contributing to population change. Harvest trends of eastern wild turkey in northeastern South Dakota suggest a decline in abundance. We investigated factors influencing reproductive success of this important game bird to identify potential factors contributing to the decline. We monitored nesting rate, nest survival, renesting rate, clutch size, hatchability, and poult survival of 116 eastern wild turkey hens using VHF radio transmitters during the springs and summers of 2017 and 2018. Heavier hens were more likely to attempt to nest than lighter hens, and adult hens were more likely to renest than yearling hens. Nest survival probability was lowest in agricultural fields relative to all other cover types and positively related to horizontal visual obstruction and distance to the nearest road. Daily nest survival probability demonstrated an interaction between temperature and precipitation, such that nest survival probability was lower on warm, wet days, but lowest on dry days. Egg predation was the leading cause of nest failure, followed by haying of the nest bowl and death of the incubating hen. Poults reared by adult hens had a greater probability of survival than poults reared by yearling hens. Our estimate of survival probability of poults raised by yearling hens was low relative to other studies, which may be contributing to the apparent regional population decline. However, there is little managers can do to influence poult survival in yearling hens. Alternatively, we found nest survival probability was lowest for nests initiated in agricultural fields. Wildlife‐friendly harvesting practices such as delayed haying or installation of flushing bars could help increase productivity of eastern wild turkey in northeastern South Dakota.
Baseline Plasma EGFR Circulating Tumour DNA Levels in a Pilot Cohort of EGFR-Mutant Limited-Stage Lung Adenocarcinoma Patients Undergoing Radical Lung Radiotherapy

The use of circulating cell-free tumour DNA (ctDNA) is established in metastatic lung adenocarcinoma to detect and monitor sensitising EGFR mutations. In early-stage disease, there is very little data supporting its role as a potential biomarker. We report on a prospective cohort of 9 limited-stage EGFR mutant lung cancer patients who were treated with radical radiotherapy. We looked at baseline plasma EGFR ctDNA and noted the detection rates to be higher in locally advanced disease. At a median follow-up of 13.5 months, an association between a detectable pre-radiotherapy plasma EGFR ctDNA and early tumour relapse (155 days vs. NR, p = 0.004) was noted. One patient with persistent plasma EGFR ctDNA predated radiological progression. The role of ctDNA in early-stage lung cancer is developing. Plasma EGFR ctDNA could be a useful biomarker in lung cancer patients undergoing radical treatments for staging, prognostication, and follow-up. These preliminary findings should be explored in larger studies.
Preventive effect of small‐leaved Kuding tea (Ligustrum robustum) on high‐diet‐induced obesity in C57BL/6J mice

Abstract Small‐leaved Kuding tea (SLKDT; Ligustrum robustum) is a traditional Chinese tea. We systematically investigated the effect of SLKDT extract on obesity. SLKDT‐controlled weight gain in mice fed a high‐fat diet. Tissue specimen results showed that the SLKDT extract alleviated liver damage and fat accumulation. Meanwhile, SLKDT extract improved dyslipidemia by decreasing total cholesterol, triglycerides, and low‐density lipoprotein cholesterol levels and increasing high‐density lipoprotein cholesterol levels. Furthermore, SLKDT extract reduced alanine aminotransferase, alkaline phosphatase, and aspartate transaminase levels in the serum and liver tissues; decreased inflammatory cytokines, including interleukin (IL)‐1β, tumor necrosis factor‐α, interferon‐γ, and IL‐6; and increased the anti‐inflammatory cytokines, IL‐4 and IL‐10. The quantitative PCR results showed that SLKDT extract upregulated the mRNA expressions of peroxisome proliferator‐activated receptor (PPAR)‐α, lipoprotein lipase, carnitine palmitoyltransferase 1, and cholesterol 7 alpha hydroxylase and downregulated PPAR‐γ and CCAAT/enhancer‐binding protein‐alpha mRNA expressions in the obese mouse livers to reduce adipocyte differentiation and fat accumulation, promote fat oxidation, and improve dyslipidemia, thereby inhibiting the immune response and alleviating liver injury. SLKDT shows a potential for preventing obesity and regulating obesity‐related syndrome, so it is possible to be further developed as a novel treatment for fighting obesity.

plained urge to rush through the meal or eat much larger amounts than before. In 2 patients, spouses observed “foraging behavior” and even the tendency to steal food from others. Initially we thought that the predictable striking amelioration of levodopa-induced dyskinesias might be the simple explanation for weight gain; however, on direct questioning it seems that this provided a major contribution in only 6 of the 14 patients and weight gain was seen in 3 patients who had little or no dyskinesia prior to pallidotomy. Nine of the 14 patients had two or more of the explanations listed in the Table accounting for weight gain. In reviewing the older literature, we found only one other description of weight gain following pallidotomy [7] and it is not mentioned at all in recent series. Ten of our patients gained more than 10 kg and many required dietary counseling. Improved nutritional status is clearly a benefit of successful pallidotomy. However, excessive weight gain also seems to be a possible risk. We would suggest that this potential consequence of pallidotomy be discussed with patients before surgery and that further research evaluating caloric intake and demands preoperatively and postoperatively be performed to provide a better understanding of this interesting observation. It is also our current practice to carry out detailed neuropsychological evaluations in all patients being considered for surgery. We have considered premorbid neuropsychological profile in assisting the decision as to which side to perform pallidotomy in patients with relatively symmetrical disability. We have also chosen not to proceed to surgery in a number of patients whom we believed were at substantial risk for decline to a state of significant cognitive disability if the changes we documented with GPi pallidotomy were superimposed on their already impaired baseline neuropsychological function. Further studies are required to define the relationship between preoperative cognitive states and the extent of postoperative neuropsychological and behavioral changes, their natural histories, and the correlation between these changes and the size and location of the GPi lesions.
Co-Chaperones in Targeting and Delivery of Misfolded Proteins to the 26S Proteasome

Protein homeostasis (proteostasis) is essential for the cell and is maintained by a highly conserved protein quality control (PQC) system, which triages newly synthesized, mislocalized and misfolded proteins. The ubiquitin-proteasome system (UPS), molecular chaperones, and co-chaperones are vital PQC elements that work together to facilitate degradation of misfolded and toxic protein species through the 26S proteasome. However, the underlying mechanisms are complex and remain partly unclear. Here, we provide an overview of the current knowledge on the co-chaperones that directly take part in targeting and delivery of PQC substrates for degradation. While J-domain proteins (JDPs) target substrates for the heat shock protein 70 (HSP70) chaperones, nucleotide-exchange factors (NEFs) deliver HSP70-bound substrates to the proteasome. So far, three NEFs have been established in proteasomal delivery: HSP110 and the ubiquitin-like (UBL) domain proteins BAG-1 and BAG-6, the latter acting as a chaperone itself and carrying its substrates directly to the proteasome. A better understanding of the individual delivery pathways will improve our ability to regulate the triage, and thus regulate the fate of aberrant proteins involved in cell stress and disease, examples of which are given throughout the review.
Habitat preferences, diet, feeding strategy and social organization of the black spider monkey (ateles paniscus paniscus linnaeus 1758) in surinam

A Socioecological Field Study. This monograph reports on a 26 month socioecological study of black spider monkeys (Ateles paniscus paniscus)in the Raleigh-vallen — Voltzberg Nature Reserve, Surinam. It recognizes the fundamental importance of food to the behavior and the regulation of population density fox this primate. It clarifies the complex temporal and spatial effects of tropical rain forest food sources on the behavior of a group of spider monkeys, concentrating on food category, food plant identity and phenology, and quantity, density and dispersion of the most important food sources. In addition, the present study describes habitat choice, optimal feeding strategy and sexual behavior of the spider monkey, and discusses implications of diet for social behavior. This study is also fundamental to conservation. Specialized in eating mature fruits, the spider monkey is a very important dispersal agent for many trees and lianes, particularly canopy species. However, the spider monkey is probably the most vulnerable monkey species in Surinam and it is disappearing rapidly throughout the remainder of its range. Unfortunately, it is large and noisy and can be easily tracked and hunted. It is largely restricted to undisturbed high forest, and consequently habitat destruction has more effect on it than on most other species. Together with its slow reproductive rate (a female gives birth only once every four or five years), this means that the species is poorly adapted to recover from exploitation. In order to implement proper measures for conservation, data on forest type preferences, diet and social behavior of the species, or on closely related species, in undisturbed areas, such as the one described in this monograph, are essential tools for assessing the potential of proposed protected areas.
SYNERGIC SUPPRESSION EFFECT OF CO-INFECTION OF CHICKEN INFECTIOUS ANEMIA VIRUS AND MAREK'S DISEASE VIRUS IN SPF CHICKENS

Twenty five one-day-old SPF chickens were co-infected with chicken infectious anemia virus(CIAV or CAV) and Marek's disease virus(MDV) and then vaccinated with some vaccines to study their synergic suppression effect on immune system and growth.The hematocrit was examined at 14,21,28 and 35 days post infection.The antibody titers were detected at 21 days post infection.Co-infected chickens showed the lowerest hematocrit and antibody titers to Newcastle dieases virus,avian influenza virus(H5/H9) and infectious bronchitits disease virus vaccines as comapred with chickens infected with either CAV or MDV.The experiment also confirmed that co-infection of CAV and MDV aggravated the severity of anemia and prolonged the clinical signs in SPF chickens.Six chickens died of co-infection,which indicated that CAV and MDV had the synergic suppression effect on immune system and increased mortality.
Application of carbon dioxide to the skin and muscle oxygenation of human lower-limb muscle sites during cold water immersion

Background Cold therapy has the disadvantage of inducing vasoconstriction in arterial and venous capillaries. The effects of carbon dioxide (CO2) hot water depend mainly on not only cutaneous vasodilation but also muscle vasodilation. We examined the effects of artificial CO2 cold water immersion (CCWI) on skin oxygenation and muscle oxygenation and the immersed skin temperature. Subjects and Methods Fifteen healthy young males participated. CO2-rich water containing CO2 >1,150 ppm was prepared using a micro-bubble device. Each subject’s single leg was immersed up to the knee in the CO2-rich water (20 °C) for 15 min, followed by a 20-min recovery period. As a control study, a leg of the subject was immersed in cold tap-water at 20 °C (CWI). The skin temperature at the lower leg under water immersion (Tsk-WI) and the subject’s thermal sensation at the immersed and non-immersed lower legs were measured throughout the experiment. We simultaneously measured the relative changes of local muscle oxygenation/deoxygenation compared to the basal values (Δoxy[Hb+Mb], Δdeoxy[Hb+Mb], and Δtotal[Hb+Mb]) at rest, which reflected the blood flow in the muscle, and we measured the tissue O2 saturation (StO2) by near-infrared spectroscopy on two regions of the tibialis anterior (TA) and gastrocnemius (GAS) muscles. Results Compared to the CWI results, the Δoxy[Hb+Mb] and Δtotal[Hb+Mb] in the TA muscle at CCWI were increased and continued at a steady state during the recovery period. In GAS muscle, the Δtotal[Hb+Mb] and Δdeoxy[Hb+Mb] were increased during CCWI compared to CWI. Notably, StO2values in both TA and GAS muscles were significantly increased during CCWI compared to CWI. In addition, compared to the CWI, a significant decrease in Tsk at the immersed leg after the CCWI was maintained until the end of the 20-min recovery, and the significant reduction continued. Discussion The combination of CO2 and cold water can induce both more increased blood inflow into muscles and volume-related (total heme concentration) changes in deoxy[Hb+Mb] during the recovery period. The Tsk-WI stayed lower with the CCWI compared to the CWI, as it is associated with vasodilation by CO2.
