Published: February 2022

Chronic hyperglycemia is associated with low response to aerobic exercise training in rodent models and humans, including reduced aerobic exercise capacity and impaired oxidative remodeling in skeletal muscle. Here, we investigated whether glucose lowering with the sodium–glucose cotransporter 2 inhibitor (SGLT2i), canagliflozin (Cana; 30 mg/kg/day), could restore exercise training response in a model of hyperglycemia (low-dose streptozotocin [STZ]). Cana effectively prevented increased blood glucose in STZ-treated mice. After 6 weeks of voluntary wheel running, Cana-treated mice displayed improvements in aerobic exercise capacity, higher capillary density in striated muscle, and a more oxidative fiber-type in skeletal muscle. In contrast, these responses were blunted or absent in STZ-treated mice. Recent work implicates glucose-induced accumulation of skeletal muscle extracellular matrix (ECM) and hyperactivation of c-Jun N-terminal kinase (JNK)/SMAD2 mechanical signaling as potential mechanisms underlying poor exercise response. In line with this, muscle ECM accretion was prevented by Cana in STZ-treated mice. JNK/SMAD2 signaling with acute exercise was twofold higher in STZ compared with control but was normalized by Cana. In human participants, ECM accumulation was associated with increased JNK signaling, low VO2peak, and impaired metabolic health (oral glucose tolerance test–derived insulin sensitivity). These data demonstrate that hyperglycemia-associated impairments in exercise adaptation can be ameliorated by cotherapy with SGLT2i.

Diabetes Mellitus
(DM) affects the biology of multipotent cardiac stem/progenitor cells (CSCs)
and adult myocardial regeneration. We assessed the hypothesis that senescence
and senescence-associated secretory phenotype (SASP) are a main mechanism of
cardiac degenerative defect in DM. Accordingly, we tested whether that ablation
of senescent CSCs would rescue the cardiac regenerative/reparative defect
imposed by DM. We obtained cardiac tissue from non-aged (50-64 years old) DM
type 2 (T2DM) and non-diabetic (NDM) patients with post-infarct cardiomyopathy
undergoing cardiac surgery. A higher ROS production in T2DM associated with an
increased number of senescent/dysfunctional T2DM-human(h)CSCs with reduced
proliferation, clonogenesis/spherogenesis and myogenic differentiation vs.
NDM-hCSCs in vitro. T2DM-hCSCs show a defined pathologic SASP. A
combination of two senolytics, Dasatinib (D) and Quercetin (Q), clears
senescent T2DM-hCSCs in vitro restoring their expansion and myogenic
differentiation capacities. In a T2DM model in young mice, diabetic status per
se (independently of ischemia and age) causes CSC senescence coupled with
myocardial pathologic remodeling and cardiac dysfunction. D+Q treatment
efficiently eliminates senescent cells, rescuing CSC function, which results in
functional myocardial repair/regeneration improving cardiac function in murine
DM. In conclusions, DM hampers CSC biology inhibiting their regenerative
potential through the induction of cellular senescence and SASP independently
from aging. Senolytics clear senescence abrogating the SASP restoring a fully
proliferative-/differentiation- competent hCSC pool in T2DM with normalization
of cardiac function.

Published: February 2022

Maturity Onset Diabetes of the Young (MODY) is an
autosomal dominant form of monogenic diabetes, reported to be caused by
variants in 16 genes. Concern has been raised about whether variants in BLK (MODY11), KLF11 (MODY7) and PAX4 (MODY9) cause MODY. We examined variant-level
genetic evidence (co-segregation with diabetes and frequency in population) for published putative pathogenic variants in these genes
and used burden testing to test gene-level evidence in a MODY cohort (n=1227) compared to population control (UK
Biobank, n=185,898). For comparison we analysed well-established causes of
MODY, HNF1A and HNF4A. The published
variants in BLK, KLF11 and PAX4 showed poor co-segregation
with diabetes (combined LOD scores ≤1.2), compared to HNF1A and HNF4A
(LOD scores >9), and are all too common to cause MODY (minor allele
frequency >4.95x10-5). Ultra-rare missense and
protein-truncating variants (PTVs) were not enriched in a MODY cohort compared
to the UK Biobank (PTVs P>0.05, missense P>0.1 for all three
genes) while HNF1A and HNF4A were enriched (P<10-6). Sensitivity
analyses using different population cohorts supported our results. Variant
and gene-level genetic evidence does not support BLK, KLF11 or PAX4 as causes of MODY. They should not be included
in MODY diagnostic genetic testing.
Stress-Strain Response of Muscle Fibers in Biceps Brachii under Dynamic Force: An Analysis of Biceps Curl Exercise
Authors: ASADİ DERESHGİ Hamid , SERBEST Kasım , BALIK Büşra , SAHIN Sema Nur
Published: February 2022

One of the most important features of endurance training was to increase the weight of the dumbbells between sets. According to the relationship of the contractile force in the muscles, the porpuse was to increase muscle growth by gaining more contractile force. Previous studies had generally examined muscle behavior under maximum force. However, the relationship between increased dumbbell weight and muscle contraction was not fully investigated. The aim of this study was to investigate the mechanical behaviors resulting from the application of dynamic forces that occur during the dumbbell curl exercise on muscle fibers. In this study, biceps brachii muscle force during biceps curl exercise performed with two different weights (5kg and 10kg) was calculated. Then, a finite element model was developed and mechanical behaviors in the biceps muscle fiber during exercise were investigated. It was achieved that there was no linear correlation between dumbbell weight and muscle force. It was observed that when dumbbell weights were doubled (100%), the maximum muscle force and deformation increased by 83.13% and 84.92%, respectively. The results showed that increasing excessive weight during exercises will not be as beneficial for muscle development as expected.
Global Standards, Corporate Diagrams and Indigenous Agency: ExxonMobil in Russia and Alaska
Authors: Tysiachniouk Maria , Henry Laura , Horowitz Leah
Published: February 2022

This paper examines how a transnational corporation (TNC) translates global standards and corporate policies into programs at sites of extraction. We explore this question through a comparative analysis of ExxonMobil’s operations in two different politico-economic contexts: the Sakhalin-1 project in Russia and the Point Thomson project on the North Slope of Alaska, with field work on Sakhalin Island in 2013–2015 and in Alaska in 2015–2018. Theoretically, we use the Deleuzian concept of “diagram” as a lens through which to examine corporate policies, and a governance generating network (GGN) approach to analyze similarities and differences in benefit-sharing programs in both localities. We show that while global commitments and corporate principles contribute to a standardized approach to community engagement, Indigenous movements and associations, the government, and other corporate actors may play important roles in influencing how corporate policies and global standards are implemented at sites of extraction. Moreover, adaptation of community engagement, benefit-sharing, and environmental monitoring in one location may shape how the company’s strategies are implemented in other sites of extraction.
Epidemiology of Brucellosis in Small Ruminants
Authors: Kebkiba Bidjeh
Published: February 2022

Brucellosis is a zoonotic infectious disease caused by a bacterium of the genus Brucella , common to certain animals, both domestic and wild, and to humans. Historically, this disease is known as Malta fever or melitococcal disease. The causative agent was isolated in 1887 on the Island of Malta by David Bruce. Its extension is worldwide with a predominance in developing countries. The determinants of the epidemiology of the disease in small ruminants in sub-Saharan Africa are not well understood and the available data are fragmentary and sometimes insufficient. This bacterial infection affects thousands of people around the world. The main clinical signs of brucellosis in small ruminants are abortion, retained placenta, stillbirth, orchitis and arthritis. Infected animals, milk and dairy products are the sources of infection in humans. B. melitensis , B. abortus and B. suis are the most important species in terms of public health and economy. Pigs are the source of almost all human contaminations. B. melitensis , the species most frequently implicated in human pathology, is largely predominant in sheep and goats. This organism contains three biovars and all of them can cause disease in small ruminants. The purpose of this article is to summarize the epidemiological data collected from bibliographic references: the causative agent of the disease, clinical manifestations, sources and modes of transmission of infection, diagnosis and prophylaxis.

Use of Natural Wastes for Biosurfactant (BS) and Bioemulsifier (BE) Production and their Applications – A Review
Authors: Shilpa Mujumdar
Published: February 2022

Commercial biosurfactant (BS) or bioemulsifier (BE) production requires high manufacturing cost and result difficulties in downstream processing and purification. This problem can be resolved by using low- cost natural substrates. Agro- industrial wastes as well as non-edible portions of fruits, vegetables, fish and meat contributes in high disposal and loss of nutritional biomass from the environment. These are readily available wastes which have tremendous potential to be reused as a substrate by microorganisms for efficient BS or BE production. Fruits, vegetables, fish, dairy and brewery wastes are rich sources of valuable nutrients which includes carbon, nitrogen, vitamins and other minerals. BS or BE produced using these substrates are stable in environment and show potential applications in many sectors of food industry, oil industry, agriculture, bioremediation, medicine and pharmaceutical industry. Yield of biosurfactant or bioemulsifier production can be increased by optimizing certain media parameters with the natural substrate concentrations. Growth parameters such as pH, temperature, salinity, carbon and nitrogen content have effect on stability of microorganism for maximum biosurfactant or bioemulsifier production. This review describes some recent developments and applications for the commercial biosurfactant or bioemulsifier production using cheap and unconventional natural wastes.

Elemen penting difusi inovasi salah satunya adalah saluran komunikasi. Setiap saluran komunikasi memiliki etika dan strategi komunikasinya masing-masing dalam upaya memengaruhi anggota suatu sistem sosial tertentu dalam mengadopsi tidaknya suatu inovasi. Penelitian ini bertujuan untuk menganalisis urgensi peran etika berkomunikasi pimpinan dalam proses difusi inovasi pembelajaran digital dilihat dari filosofi hidup anggota sistem sosial tempat difusi inovasi terjadi. Metode penelitian yang digunakan adalah metode penelitian deskriptif (cross-sectional study) dengan menggunakan metode survey. Hasil analisis menunjukkan bahwa peran etika berkomunikasi dalam proses difusi inovasi pembelajaran digital pada sistem persekolahan sangat urgen pada aspek-aspek: pihak yang wenang mengkomunikasikan, komunikasi interpersonal para pimpinan yang simetris, dan penghargaan terhadap lingkungan dan masyarakat melalui pendekatan konflik kepentingan, dan tanggung jawab sosial. Dapat disimpulkan bahwa ditinjau dari filosofi hidup masyarakat Bali, etika komunikasi pimpinan dalam proses difusi inovasi pada sistem persekolahan sangat nampak pada aspek penghargaan terhadap lingkungan yakni pendekatan konflik kepentingan difusi inovasi. Tulisan awal ini masih perlu disempurnakan dengan data empiris lebih lanjut di lapangan, sehingga dapat memberikan gambaran menyeluruh keterkaitan difusi inovasi dengan faktor-faktor yang potensial memengaruhi diadopsi tidaknya inovasi pada satu atau lebih sistem sosial persekolahan lainnya.
