This study determined the time course for changes in muscle swelling and plasma volume following high (HI) and low-intensity resistance exercise with blood-flow restriction (LI-BFR). Ten male participants (22.1±3.0 yrs) completed three experimental conditions: high-intensity exercise (HI - 80% of 1RM), low-intensity exercise with BFR (LI-BFR -20% of 1RM, and 160 mmHg of BFR), and control (CON - no exercise or BFR). Muscle cross-sectional area (mCSA), muscle thickness, thigh circumference, and percentage change in plasma volume (PV%∆) were measured. mCSA was significantly greater than rest values at 15 min post-exercise (p<0.01) for HI and LI-BFR, and at 75 min post-exercise (p<0.01) for HI. Muscle thickness was significantly greater than rest immediately post-exercise (p<0.01) and 30 min post-exercise (p<0.01) for HI and LI-BFR, and at 60 min post-exercise for HI (p=0.01). Muscle thickness was greater for BFR immediately post-exercise compared to HI (p=0.01) post-exercise. Thigh circumference was significantly greater from rest at 15 min post-exercise (p=0.01) and at 75 min post-exercise for both LI-BFR (p=0.03) and HI (p<0.01). PV%∆ significantly decreased from rest immediately post-exercise for both HI (p<0.01) and LI-BFR (p<0.01). In conclusion, BFR exercise induces changes in muscle swelling and plasma volume similar to those observed at high-intensities.

IntroductionPoor access to quality healthcare is one of the most important reasons of high maternal and neonatal mortality in India, particularly in poorer states like Bihar. India has implemented initiatives to promote institutional maternal deliveries. It is important to ensure that health facilities are adequately equipped and staffed to provide quality care for mothers and newborns.MethodsWe conducted a cross-sectional study of 190 primary health centres (PHCs) and 36 district hospitals (DHs) across all districts in Bihar to assess the readiness of facilities to provide quality maternal and neonatal care. Infrastructure, equipment and supplies and staffing were assessed using the WHO service availability and readiness assessment and Indian public health standard guidelines. Additionally, we used household survey data to assess the quality of care reported by mothers delivering at study facilities.ResultsPHCs and DHs were found to have 61% and 67% of the mandated structural components to provide maternal and neonatal care, on average, respectively. DHs were, on average, slightly better equipped in terms of infrastructure, equipment and supplies by comparison to PHCs. DHs were found to be inadequately prepared to provide neonatal care. Lack of recommended handwashing stations and bins at both DHs and PHCs suggested low levels of hygiene. Only half of the essential drugs were available in both DHs and PHCs. While no association was revealed between structural capacity and patient-reported quality of care, adequacy of staffing was positively associated with the quality of care in DHs.ConclusionExamining all DHs and a representative sample of PHCs in Bihar, this study revealed the gaps in structural components that need to be filled to provide quality care to mothers and newborns. Access to quality care is essential if progress in reducing maternal and neonatal mortality is to be achieved in this high-burden state.

Internal marketing has been an area of interest for the past few decades, and the rapid growth on internal marketing literature has evolved the concept further. However, this theoretical advancement has not been able to empirically strengthen the concept, and there exists disagreement on the key components of internal marketing. Thus, this article endeavours to identify the dimensions of internal marketing by probing in the extant literature. In addition, the aim of the article was to develop a robust and valid instrument for measuring internal marketing. Data were collected from qualitative study and from 154 employees of financial service sector. Analyses revealed 11 significant dimensions of internal marketing, namely, senior leadership and vision, inter-functional coordination, internal communications, organization structure and changes, staffing, training and development, incentive systems, physical environment, strategic rewards and empowerment. Construct validity and reliability were empirically ascertained along with the determination of the good fit for the proposed model. The study highlighted the difference between strategic rewards and incentive systems as perceived by the employees. In addition, organization structure and change factors were tested to be significant, providing empirical evidence of their vital role in developing and implementing internal marketing practices in service firms. The article concludes by discussing the possible implications and future research avenues.

Miller, RM, Freitas, EDS, Heishman, AD, Koziol, KJ, Galletti, BAR, Kaur, J, and Bemben, MG. Test-retest reliability between free weight and machine-based movement velocities. J Strength Cond Res XX(X): 000-000, 2018-Several devices are available to measure muscular power through velocity measurement, including the Tendo FitroDyne. The ability for such devices to produce consistent results is still questioned, and the reproducibility of measurement between free weight and machine exercise has yet to be examined. Therefore, the aim of this investigation was to determine the test-retest reliability for barbell velocity during the bench press (BP) and weight velocity during the 2 leg press (2LP) for loads corresponding to 20-80% of 1 repetition maximum (1RM). Forty recreationally active individuals (22.6 ± 2.5 years; 175.9 ± 10.8 cm; and 76.2 ± 13.2 kg) with a 1RM BP and 2LP of 66.8 ± 32.4 kg and 189.5 ± 49 kg, respectively, volunteered for this study. Subjects completed 1 familiarization visit preceding 3 testing visits, which encompassed 1RM determination and 2 days of velocity testing. Forty-eight hours after 1RM testing, the subjects performed 1 repetition at 20, 30, 40, 50, 60, 70, and 80% of their 1RM for each exercise in randomized order. Subjects returned to the laboratory 1 week later to perform the velocity assessment again in randomized order. Intraclass correlation coefficient (ICC2,1) and relative SEM for the BP and 2LP ranged from 0.56 to 0.98 (3-18.1%) and 0.78 to 0.98 (2.8-7.2%), respectively, and no mean differences were observed between trials. The results suggest high reliability for BP velocity between 30 and 60% 1RM and moderate reliability at 20, 70, and 80% 1RM, while the 2LP displayed high to excellent reliability from 20 to 80% 1RM. Cumulatively, machine-based exercise displayed greater reproducibility; however, additional machine exercises need to be examined to bolster this conclusion.

Purpose Indian banking sector is facing a number of challenges, and increasing number of corporate frauds and employee turnover are among the top list. Literature reveals that gaining insights about ethical climate may provide a possible solution and relief from the challenges being faced. This paper aims to contribute to the understanding of the prevalent various ethical climate types in the Indian banking industry. Furthermore, it presents interesting results by investigating the effect of five theorized ethical climate types on organizational commitment along with its three components in the banking sector. Design/methodology/approach This empirical research encompasses a descriptive research design. Sample uses 266 respondents from four prime banks of the Indian banking industry. Findings Statistical analyses unveiled that all five conceptualized ethical climate types are prevalent in the Indian banking industry. However, the perception of employees for caring climate was the highest among all others. In contrast to the results reported by Western studies, this research reveals a strong negative impact of instrumental climate on affective commitment. Furthermore, it has been seen that instrumental climate is a significant predictor for the three components of commitment (affective, continuance and normative). However, it fails to predict the overall organizational commitment construct. Likewise, opposed to findings of Western countries, law and code, rules and independent climate types have shown significant relationship and impact on organizational commitment for Indian banking sector employees. It has been found that different commitment components are predicted by a diverse mix of climate types in India. Practical implications Findings highlight varying strength of relationship and predictive ability of different ethical climate types with commitment. This helps in elucidating that managers and top executives should focus on building an ethical work environment to warrant high-level commitment among employees. Congruence between employee, manager and organizations’ perception of ethics is a pre-requisite for maintaining a long-term relationship among the parties. This study will enable understanding the role of ethical climate in reducing corporate frauds and employee turnover. Originality/value This research addresses a significant gap in literature by exploring the relationship between ethical climate and organizational commitment. The study uses data from the Indian banking industry which contributes to expanding knowledge of the relationship in the Indian context.

Estrogen is known to regulate bone metabolism in both women and men, but substantial gaps remain in our knowledge of estrogen and estrogen receptor alpha (ERα) regulation of adult bone metabolism. Studies using global ERα‐knockout mice were confounded by high circulating sex‐steroid levels, and osteocyte/osteoblast‐specific ERα deletion may be confounded by ERα effects on growth versus the adult skeleton. Thus, we developed mice expressing the tamoxifen‐inducible CreERT2 in osteocytes using the 8‐kilobase (kb) Dmp1 promoter (Dmp1CreERT2). These mice were crossed with ERαfl//fl mice to create ERαΔOcy mice, permitting inducible osteocyte‐specific ERα deletion in adulthood. After intermittent tamoxifen treatment of adult 4‐month‐old mice for 1 month, female, but not male, ERαΔOcy mice exhibited reduced spine bone volume fraction (BV/TV (−20.1%, p = 0.004) accompanied by decreased trabecular bone formation rate (−18.9%, p = 0.0496) and serum P1NP levels (−38.9%, p = 0.014). Periosteal (+65.6%, p = 0.004) and endocortical (+64.1%, p = 0.003) expansion were higher in ERαΔOcy mice compared to control (Dmp1CreERT2) mice at the tibial diaphysis, reflecting the known effects of estrogen to inhibit periosteal apposition and promote endocortical formation. Increases in Sost (2.1‐fold, p = 0.001) messenger RNA (mRNA) levels were observed in trabecular bone at the spine in ERαΔOcy mice, consistent with previous reports that estrogen deficiency is associated with increased circulating sclerostin as well as bone SOST mRNA levels in humans. Further, the biological consequences of increased Sost expression were reflected in significant overall downregulation in panels of osteoblast and Wnt target genes in osteocyte‐enriched bones from ERαΔOcy mice. These findings thus establish that osteocytic ERα is critical for estrogen action in female, but not male, adult bone metabolism. Moreover, the reduction in bone formation accompanied by increased Sost, decreased osteoblast, and decreased Wnt target gene expression in ERαΔOcy mice provides a direct link in vivo between ERα and Wnt signaling. © 2022 American Society for Bone and Mineral Research (ASBMR).

Senescence drives organismal aging, yet the deep characterization of senescent cells in vivo remains incomplete. Here, we applied mass cytometry by time-of-flight (CyTOF) using carefully validated antibodies to analyze senescent cells at single-cell resolution. We used multiple criteria to identify senescent mesenchymal cells that were growth arrested and resistant to apoptosis (p16+/Ki67-/BCL-2+; p16KB cells). These cells were highly enriched for senescence-associated secretory phenotype (SASP) and DNA damage markers and were strongly associated with age. p16KB cell percentages were also increased in CD24+ osteolineage cells, which exhibited an inflammatory SASP in aged mice and were robustly cleared by both genetic and pharmacologic senolytic therapies. Following isolation, CD24+ skeletal cells exhibited growth arrest, SA-beta gal positivity, and impaired osteogenesis in vitro. These studies thus provide a new approach using multiplexed protein profiling by CyTOF to define senescent mesenchymal cells in vivo and identify a highly inflammatory, senescent CD24+ osteolineage population cleared by senolytics.
