Barocrinology: The Endocrinology of Obesity from Bench to Bedside

Obesity has reached pandemic proportions. Hormonal and metabolic imbalances are the key factors that lead to obesity. South Asian populations have a unique phenotype, peculiar dietary practices, and a high prevalence of consanguinity. Moreover, many lower middle-income countries lack appropriate resources, super-specialists, and affordability to manage this complex disorder. Of late, there has been a substantial increase in both obesity and diabesity in India. Thus, many more patients are being managed by different types of bariatric procedures today than ever before. These patients have many types of endocrine and metabolic disturbances before and after bariatric surgery. Therefore, these patients should be managed by experts who have knowledge of both bariatric surgery and endocrinology. The authors propose “Barocrinology”, a novel terminology in medical literature, to comprehensively describe the field of obesity medicine highlighting the role of knowing endocrine physiology for understating its evolution, insights into its complications and appreciating the changes in the hormonal milieu following weight loss therapies including bariatric surgery. Barocrinology, coined as a portmanteau of “baro” (weight) and endocrinology, focuses upon the endocrine and metabolic domains of weight physiology and pathology. This review summarizes the key pointers of bariatric management from an endocrine perspective.
Antidiarrheal Effect of Sechang-Zhixie-San on Acute Diarrhea Mice and Network Pharmacology Deciphering Its Characteristics and Potential Mechanisms

Sechang-Zhixie-San (SCZX) is an ancient prescription used for pediatric diarrhea by the Yi people in China, which consists of Rodgersia sambucifolia Hemsley (known as Yantuo and abbreviated as YT) and Bentonite (BN). Now, it is also a Chinese patent medicine used in the clinic to treat infantile diarrhea. Besides evaluating the antidiarrheal effect of SCZX on diarrhea mice induced by Folium Sennae, the purpose of this study is to outline the characteristics of the antidiarrheal effect and reveal the potential mechanisms of SCZX through the analysis of the mechanism and active components of YT via network pharmacology and molecular docking, combined with the research progress of BN obtained from the literature. SCZX (3.12 and 12.48 g/kg) effectively inhibited diarrhea in mice, significantly lowering the loose stool rate (LSR), loose stool level (LSL), and loose stool index (LSI). Using network pharmacology, the “herb-compound-target-pathway-pharmacological action” network was mapped to indicate the antidiarrheal mechanism of YT. And the docking results revealed that 4 components of YT including quercetin, geranyl-1-O-α-L-arabinopyranosyl-(1 ⟶ 6)-β-D-glucopyranoside, 3α-O-(E)-p-hydroxy-cinnamoyl-olean-12-en-27-oic acid, and daucosterol showed significant docking activities with STAT3, EGFR, and SLC10A2, involving 11 pathways such as Th17 cell differentiation, Jak-STAT signaling pathway, ErbB signaling pathway, and HIF-1 signaling pathway. According to our research results and literature reports, the antidiarrheal could be summarized into five aspects: inhibiting intestinal inflammation, acting as a barrier to the intestinal mucosal, regulating water and ion transport, involving the purification of intestinal microorganisms, and intestinal transmission, which might be dependent on multiple proteins and intervention in multiple pathways.
Coadministration of Ketamine and Perampanel Improves Behavioral Function and Reduces Inflammation in Acute Traumatic Brain Injury Mouse Model

Traumatic brain injury (TBI) is among the most debilitating neurological disorders with inadequate therapeutic options. It affects all age groups globally leading to post-TBI behavioral challenges and life-long disabilities requiring interventions for these health issues. In the current study, C57BL/6J mice were induced with TBI through the weight-drop method, and outcomes of acutely administered ketamine alone and in combination with perampanel were observed. The impact of test drugs was evaluated for post-TBI behavioral changes by employing the open field test (OFT), Y-maze test, and novel object recognition test (NOR). After that, isolated plasma and brain homogenates were analyzed for inflammatory modulators, i.e., NF-κB and iNOS, through ELISA. Moreover, metabolomic studies were carried out to further authenticate the TBI rescuing potential of drugs. The animals treated with ketamine-perampanel combination demonstrated improved exploratory behavior in OFT (P < 0.05), while ketamine alone as well as in combination yielded anxiolytic effect (P < 0.05‐0.001) in posttraumatic mice. Similarly, the % spontaneous alternation and % discrimination index were increased after the administration of ketamine alone (P < 0.05) and ketamine-perampanel combination (P < 0.01‐0.001) in the Y-maze test and NOR test, respectively. ELISA demonstrated the reduced central and peripheral expression of NF-κB (P < 0.05) and iNOS (P < 0.01‐0.0001) after ketamine-perampanel polypharmacy. The TBI-imparted alteration in plasma metabolites was restored by drug combination as evidenced by metabolomic studies. The outcomes were fruitful with ketamine, but the combination therapy proved more significant in improving all studied parameters. The benefits of this new investigated polypharmacy might be due to their antiglutamatergic, antioxidant, and neuroprotective capacity.
Reversible coordination changes in crystalline silicates at high pressure and ambient temperature

In silicates, generally the less dense open structures of lower pressure polymorphs have four-coordinated silicon whereas the denser more close-packed structures have six-coordinated silicon. Transformation from the fourfold coordinated crystals to the denser sixfold coordinated structures upon compression usually requires an accompanying high temperature that is much greater than ambient. We report here a first-order, reversible SiO4 -SiO6 coordination change in a crystalline silicate (MgSiO3 ) orthoenstatite at ambient temperature and quasi-hydrostatic conditions using Raman spectroscopic measurements in a diamond cell to 70 GPa. Annealing experiments using a CO2 laser, which controlled defect concentration, indicate that the four- to sixfold coordination change is facilitated by defects in the structure which may serve as nucleation sites for the formation of the octahedrally coordinated silicon phase.
Mouse mutant phenotyping at scale reveals novel genes controlling bone mineral density

The genetic landscape of diseases associated with changes in bone mineral density (BMD), such as osteoporosis, is only partially understood. Here, we explored data from 3,823 mutant mouse strains for BMD, a measure that is frequently altered in a range of bone pathologies, including osteoporosis. A total of 200 genes were found to significantly affect BMD. This pool of BMD genes comprised 141 genes with previously unknown functions in bone biology and was complementary to pools derived from recent human studies. Nineteen of the 141 genes also caused skeletal abnormalities. Examination of the BMD genes in osteoclasts and osteoblasts underscored BMD pathways, including vesicle transport, in these cells and together with in silico bone turnover studies resulted in the prioritization of candidate genes for further investigation. Overall, the results add novel pathophysiological and molecular insight into bone health and disease.
Grundlagen des Agglomerierens

Principles of agglomeration. Particle cohesion is first discussed in connection with agglomeration processes. In this context, the author compiles both the theoretical fundamentals and the most important aspects of partical significance which have so far resisted theoretical description. A basis then exists for formulation of the main principles of various agglomeration processes. The purpose of the processes is to produce agglomerates having particular properties. The principal methods of determining such properties are surveyed. Attention is focussed on recent work both in particle cohesion and in the characterization of agglomerates.
Optimal adjustment of the human circadian clock in the real world

Which suggestions for behavioral modifications, based on mathematical models, are most likely to be followed in the real world? We address this question in the context of human circadian rhythms. Jet lag is a consequence of the misalignment of the body’s internal circadian (~24-hour) clock during an adjustment to a new schedule. Light is the clock’s primary synchronizer. Previous research has used mathematical models to compute light schedules that shift the circadian clock to a new time zone as quickly as possible. How users adjust their behavior when provided with these optimal schedules remains an open question. Here, we report data collected by wearables from more than 100 travelers as they cross time zones using a smartphone app, Entrain. We find that people rarely follow the optimal schedules generated through mathematical modeling entirely, but travelers who better followed the optimal schedules reported more positive moods after their trips. Using the data collected, we improve the optimal schedule predictions to accommodate real-world constraints. We also develop a scheduling algorithm that allows for the computation of approximately optimal schedules "on-the-fly" in response to disruptions. User burnout may not be critically important as long as the first parts of a schedule are followed. These results represent a crucial improvement in making the theoretical results of past work viable for practical use and show how theoretical predictions based on known human physiology can be efficiently used in real-world settings.
gga-miR-1603 and gga-miR-1794 directly target viral L gene and function as a broad-spectrum antiviral factor against NDV replication

ABSTRACT As the causative agent of Newcastle disease (ND), Newcastle disease virus (NDV) has seriously restricted the development of the poultry industry. Previous research has shown that miRNAs, members of the small noncoding RNA family, are implicated in the regulation NDV replication through extensive interactions with host mRNAs, but whether miRNAs affect NDV replication by directly binding to the NDV antigenome remains unclear. In this study, potential Gallus gallus miRNAs targeting the antigenome of NDV were bioinformatically predicted using the online software RegRNA 2.0, and gga-miR-1603 and gga-miR-1794 were identified as targeting the viral L gene directly through dual-luciferase reporter assays. Sequence alignment analysis demonstrated that multiple genotypes of NDVs harbored highly conserved binding sites for gga-miR-1603 and gga-miR-1794 in the viral antigenome located at 8611–8634 nt and 14,490–14,514 nt, respectively. Meanwhile, we found that gga-miR-1603 and gga-miR-1794 negatively regulated the expression of viral L gene at both the RNA and protein levels, as well as viral replication in vitro. Furthermore, NDV infection had no effect on endogenous gga-miR-1603 and gga-miR-1794 expression in various avian cell lines. Overall, our present study demonstrated that gga-miR-1603 and gga-miR-1794 directly bind to the viral L gene to facilitate ts degradation and inhibit the replication of multiple genotypes of NDVs in vitro. These findings will provide us with important clues for antiviral therapy against NDV infection.
Speech Segregation in Active Middle Ear Stimulation: Masking Release With Changing Fundamental Frequency

Objectives: Temporal fine structure information such as low-frequency sounds including the fundamental frequency (F0) is important to separate different talkers in noisy environments. Speech perception in noise is negatively affected by reduced temporal fine structure resolution in cochlear hearing loss. It has been shown that normal-hearing (NH) people as well as cochlear implant patients with preserved acoustic low-frequency hearing benefit from different F0 between concurrent talkers. Though patients with an active middle ear implant (AMEI) report better sound quality compared with hearing aids, they often struggle when listening in noise. The primary objective was to evaluate whether or not patients with a Vibrant Soundbridge AMEI were able to benefit from F0 differences in a concurrent talker situation and if the effect was comparable to NH individuals. Design: A total of 13 AMEI listeners and 13 NH individuals were included. A modified variant of the Oldenburg sentence test was used to emulate a concurrent talker scenario. One sentence from the test corpus served as the masker and the remaining sentences as target speech. The F0 of the masker sentence was shifted upward by 4, 8, and 12 semitones. The target and masker sentences were presented simultaneously to the study subjects and the speech reception threshold was assessed by adaptively varying the masker level. To evaluate any impact of the occlusion effect on speech perception, AMEI listeners were tested in two configurations: with a plugged ear-canal contralateral to the implant side, indicated as AMEIcontra, or with both ears plugged, indicated as AMEIboth. Results: In both study groups, speech perception improved when the F0 difference between target and masker increased. This was significant when the difference was at least 8 semitones; the F0-based release from masking was 3.0 dB in AMEIcontra (p = 0.009) and 2.9 dB in AMEIboth (p = 0.015), compared with 5.6 dB in NH listeners (p < 0.001). A difference of 12 semitones revealed a F0-based release from masking of 3.5 dB in the AMEIcontra (p = 0.002) and 3.4 dB in the AMEIboth (p = 0.003) condition, compared with 5.0 dB in NH individuals (p < 0.001). Conclusions: Though AMEI users deal with problems resulting from cochlear damage, hearing amplification with the implant enables a masking release based on F0 differences when F0 between a target and masker sentence was at least 8 semitones. Additional occlusion of the ear canal on the implant side did not affect speech performance. The current results complement the knowledge about the benefit of F0 within the acoustic low-frequency hearing.
Influence of Psychotic Episodes on Grey Matter Volume Changes in Patients with Schizophrenia.

BACKGROUND Schizophrenia is a severe illness whose clinical course is characterized by various numbers of psychotic episodes (PE). The neurotoxic hypothesis (NH) of schizophrenia assumes that psychosis is biologically toxic. The aim of the study was to investigate whether schizophrenia patients (SP) with multiple PE have greater grey matter volume (GMV) reduction compared to SP with fewer PE. SUBJECTS AND METHODS We enrolled 106 adult SP and 63 healthy controls. Demographic and clinical data were collected and statistically analysed for all included subjects. Magnetic resonance imaging (MRI) of the brain was acquired on a 1.5 T scanner. SP were grouped according to the number of PE into a group with up to 3 PE (SCHG-1) and with 4 or more PE (SCHG-2). SCHG-1 was further subdivided into two groups regarding to disease duration (DD). Voxel-based morphometry (VBM) analyses were performed between SP groups as well as between SP groups and the healthy controls group (HCG). RESULTS No relevant GMV differences were detected between SP groups. Comparison between HCG and SCHG-1 showed only 3 regions with reduced GMV, while multiple regions with reduced GMV were detected when comparing HCG and SCHG-2. CONCLUSIONS GMV reduction in schizophrenia varies depending on the number of PE when compared to HCG, regardless of disease duration (DD), but PE is not the only contributing factor that leads to neurotoxicity.
Heparin induced thrombocytopenia: position paper from the Italian Society on Thrombosis and Haemostasis (SISET).

Heparin induced thrombocytopenia (HIT) is a rare immune mediated adverse drug reaction occurring after exposure to heparin. It is a serious and potentially fatal condition, which may be associated with the development of arterial or venous thrombotic events. Although known for many years, HIT is still often misdiagnosed. Pre-test clinical probability, screening for anti-PF4/heparin antibodies and documentation of their platelet activating capacity are the cornerstones of diagnosis. However, both clinical algorithms and test modalities have limited predictive values and limited diffusion so that the diagnosis and management is challenging in the clinical practice. For this reason, there is an unmet need for novel rational non-anticoagulant therapies based on the pathogenesis of HIT.The present paper reports the position of the Italian Society on Haemostasis and Thrombosis (SISET) in order to increase awareness of HIT among clinicians and other health care professionals and to provide information on the most appropriate management.
Hispanic Identity and Its Inclusion in the Race Discrimination Discourse in the United States.

As protests against racism occur all over the United States and medical institutions face calls to incorporate antiracism and health equity curricula into professional training and patient care, the antiracism discourse has largely occurred through a Black/African American and White lens. Hispanics, an umbrella category created by the U.S. government to include all people of Spanish-speaking descent, are the largest minority group in the country. Hispanics are considered an ethnic rather than a racial group, although some Hispanics self-identify their race in terms of their ethnicity and/or country of origin while other Hispanics self-identify with any of the 5 racial categories used by the U.S. government (White, Black or African American, American Indian or Alaska Native, Asian, or Native Hawaiian or Other Pacific Islander). Expanding the antiracism discourse in medicine to include Hispanic perspectives and the diversity of histories and health outcomes among Hispanic groups is crucial to addressing inequities and disparities in health and medical training. A lack of inclusion of Hispanics has contributed to a growing shortage of Hispanic physicians and medical school faculty in the United States as well as discrimination against Hispanic physicians, trainees, and patients. To reverse this negative trend and advance a health care equity and antiracist agenda, the authors offer steps that medical schools, academic medical centers, and medical accreditation and licensing bodies must take to increase the representation of Hispanics and foster their engagement in this evolving antiracism discourse.
Double Jeopardy Versus Double Benefit: The Role of Age and Leisure Activities in the Incidence of Disability Among Chinese Older Adults

Objectives: This paper analyzes the double jeopardy effect of age and double benefit of leisure activities in the incidence of disability. Methods: This study uses data from the Chinese Longitudinal Healthy Longevity Survey between 2002 and 2014. Disability status is measured by activities of daily living. Leisure activities include physical and social activities. A generalized linear mixed model with a time-lag design is used to analyze the trajectory of being disabled. Results: Older ages are associated with double jeopardy of disability: higher initial probability and faster pace. The double benefit of leisure activities is confirmed: lower initial probability and a slower pace of change in disability over time. The age pattern is substantially alleviated when leisure activities and other covariates are present. Discussion: Although the risk of disability rises with advancing age, the over-time trajectory can be flattened by engagement in leisure activities and other factors.
Determination Of Levels Of Lead And Cadmium Contamination In Meat Products Sold In Northern Lebanese Markets

The levels of lead and cadmium have been determined in canned and processed meat products sold in North Lebanon. Such products are normally available all year round in the markets. Never before have these meat products been assessed for their levels of toxic metals nor have they been given the deserved attention regarding their impact on human health. Using closed-vessel microwave acid-assisted digestion and graphite furnace atomic absorption spectroscopy, the levels of lead (Pb) and cadmium (Cd) were determined in 75 brands of canned and 33 brands of processed (cold cuts) meat sold in the northern part of the country. The data provided extremely important information to whether or not Lebanese individuals are exposed to high levels of such toxic metals where specifi cally children were found to be more vulnerable to such exposures. In canned meat, the data showed that the levels of Pb ranged from 0.00020 to 0.8161 µg/g with a mean of 0.02696 µg/g, while 29 brands were below the detectable limit. As for Cd, the data revealed levels ranging from 0.00019 to 0.1382 µg/g with a mean of 0.01557 µg/g, while seven brands were below the detectable limit. In processed meat samples, Pb concentrations ranged from 0.00025 to 0.06135 µg/g with a mean of 0.0174 µg/g of which three brands showed nondetectable levels. Concentrations of cadmium ranged from 0.0000245 to 0.0071 µg/g where the mean concentration was found to be 0.002386 µg/g. Two major parameters, amount consumed and body weight, were found to play an important role in determining whether the provisional Tolerable Weekly Intake levels (PTWIs) of Pb and Cd were exceeded or not. Specifi cally for canned meats, certain samples have shown that the PTWI has been markedly exceeded in children for both metals.
Long non-coding RNA TUSC7 suppressed colorectal cancer progression via regulation of miR-23b/PDE7A Axis.

PURPOSE Despite advances in our understanding of the roles of the long noncoding RNA (lncRNA) tumor suppressor candidate 7 (TUSC7) in cancer biology, which has been identified to act as a tumor suppressor by regulating cell proliferation, apoptosis, migration, invasion, cell cycle and tumor growth, its function in colorectal cancer remains unknown. METHODS The expression levels of TUSC7 in colorectal cancer tissues and cell lines were determined, and the biological functions of TUSC7 to cancer progression in colorectal cancer were investigated via correlation analysis of clinical samples, cell viability assay, transwell assay and apoptosis analysis. Further, the molecular regulatory mechanisms of TUSC7 were demonstrated by luciferase reporter assay and western blotting. RESULTS We observed that the expression of TUSC7 was markedly decreased in colorectal cancer cell lines. Moreover, the lower expression of TUSC7 was correlated with advanced clinical grades and poorer survival and may be an independent risk factor for colorectal cancer. Moreover, the expression of TUSC7 inhibited cell proliferation, invasion and epithelial-to-mesenchymal transition (EMT), while it facilitated apoptosis through competitively binding miR-23b. We also found that TUSC7 decreased the expression of phosphodiesterase 7A (PDE7A), a downstream target of miR-23b, through the TUSC7/miR-23b/PDE7A axis. CONCLUSION We demonstrated the expression of TUSC7 suppressed colorectal cancer progression through the TUSC7/miR-23b/PDE7A axis, suggesting that TUSC is a potential target for therapeutic intervention in colorectal cancer.
