Characterization of Mmp37p, a \u3cem\u3eSaccharomyces cerevisiae\u3c/em\u3e Mitochondrial Matrix Protein with a Role in Mitochondrial Protein Import
Many mitochondrial proteins are encoded by nuclear genes and after translation in the cytoplasm are imported via translocases in the outer and inner membranes, the TOM and TIM complexes, respectively. Here, we report the characterization of the mitochondrial protein, Mmp37p (YGR046w) and demonstrate its involvement in the process of protein import into mitochondria. Haploid cells deleted of MMP37 are viable but display a temperature-sensitive growth phenotype and are inviable in the absence of mitochondrial DNA. Mmp37p is located in the mitochondrial matrix where it is peripherally associated with the inner membrane. We show that Mmp37p has a role in the translocation of proteins across the mitochondrial inner membrane via the TIM23-PAM complex and further demonstrate that substrates containing a tightly folded domain in close proximity to their mitochondrial targeting sequences display a particular dependency on Mmp37p for mitochondrial import. Prior unfolding of the preprotein, or extension of the region between the targeting signal and the tightly folded domain, relieves their dependency for Mmp37p. Furthermore, evidence is presented to show that Mmp37 may affect the assembly state of the TIM23 complex. On the basis of these findings, we hypothesize that the presence of Mmp37p enhances the early stages of the TIM23 matrix import pathway to ensure engagement of incoming preproteins with the mtHsp70p/PAM complex, a step that is necessary to drive the unfolding and complete translocation of the preprotein into the matrix

Antioxidant activity of β-lactoglobulin and its modified derivatives
Both native ss-lactoglobulin and its modified derivatives (Figure 1) exhibited antioxidant activity when assessed by the FRAP assay (which measures total reducing power of the sample). A positive correlation was observed between antioxidant activity and protein concentration in all samples. Compared to the native protein, the concentration dependence of the antioxidant activity was significantly greater when ss-lactoglobulin was modified with the Maillard reaction (p=0.000) and Enzyme hydrolysis (p=0.022)....<br /
Literacy and numeracy support in vocational education: Perceptions from engineering apprentices in victoria
This research explored how engineering apprentices at an Australian TAFE institution perceive their supported acquisition of literacy and numeracy skills. Using a mixed methods approach, 56 apprentices completed questionnaires with nine participating in subsequent interviews. The study identified apprentices’ perceived ability levels in reading, writing and numeracy, learning strategies they employed, and literacy and numeracy support they found most helpful. Findings provide insight into apprentices’ approaches to learning, many of whom struggled to articulate how they acquired the literacy and numeracy skills for their studies and employment. Participants primarily focused on navigation of coursework and reading demands while reporting similar learning strategies. Literacy and numeracy support (LNS) teachers were considered helpful for others, with clear distinctions between the trade teacher/trainer and LNS teacher. Agitation with the self-paced nature of the classroom and a mismatch between study and workplace was also highlighted. This research suggests greater awareness of how apprentices learn would support literacy and numeracy skills development without reinforcing a deficit discourse. New approaches to develop apprentices’ learning strategies within the wider dialogue of literacy and numeracy acquisition is recommended. © 2021, Western Australian Institute for Educational Research Inc..

Profile of repeat victimisation within multi-agency referrals
To help reduce victimisation, safeguarding practices in England and Wales are becoming more
multi-agency, with Multi-Agency Safeguarding Hubs (MASH) being a contemporary example of
such an approach. MASH aims to reduce victimisation by identifying and managing vulnerability at
the earliest opportunity. This is achieved through the co-location of safeguarding agencies, joint
decision making and the co-ordination of interventions. Previous research has indicated that the
demand placed upon MASH often outweighs available resources, questioning the extent to which
MASH effectively safeguards vulnerable people at the earliest opportunity. Whilst existing literature
has focused upon the characteristics of MASH referrals, alongside referral processes, rates of
repeat referrals have been overlooked. This paper aims to bridge this gap by exploring the number
of repeat referrals made over a two-month period to a MASH location in the north-west of
England (n ÂĽ 2,134). By investigating repeat referrals, reasons why some individuals are susceptible
to being victimised on multiple occasions are identified. The paper concludes that whilst MASH has
taken a step towards identifying and managing victimisation, practices and processes need to be
reviewed if MASH is to proactively prevent repeat victimisation
Neurodevelopmental Changes in Social Reinforcement Processing: A Functional Magnetic Resonance Imaging Study.
ObjectiveIn the current study we investigated neurodevelopmental changes in response to social and non-social reinforcement.MethodsFifty-three healthy participants including 16 early adolescents (age, 10-15 years), 16 late adolescents (age, 15-18 years), and 21 young adults (age, 21-25 years) completed a social/non-social reward learning task while undergoing functional magnetic resonance imaging. Participants responded to fractal image stimuli and received social or non-social reward/non-rewards according to their accuracy. ANOVAs were conducted on both the blood oxygen level dependent response data and the product of a context-dependent psychophysiological interaction (gPPI) analysis involving ventromedial prefrontal cortex (vmPFC) and bilateral insula cortices as seed regions.ResultsEarly adolescents showed significantly increased activation in the amygdala and anterior insula cortex in response to non-social monetary rewards relative to both social reward/non-reward and monetary non-rewards compared to late adolescents and young adults. In addition, early adolescents showed significantly more positive connectivity between the vmPFC/bilateral insula cortices seeds and other regions implicated in reinforcement processing (the amygdala, posterior cingulate cortex, insula cortex, and lentiform nucleus) in response to non-reward and especially social non-reward, compared to late adolescents and young adults.ConclusionIt appears that early adolescence may be marked by: (i) a selective increase in responsiveness to non-social, relative to social, rewards; and (ii) enhanced, integrated functioning of reinforcement circuitry for non-reward, and in particular, with respect to posterior cingulate and insula cortices, for social non-reward
Dynamic structure elucidation of chemical reactivity by laser pulses and X-ray probes
Visualising chemical reactions by X-ray methods is a tantalising prospect. New light sources provide the prospect for studying atomic, electronic and energy transfers accompanying chemical change by X-ray spectroscopy and inelastic scattering. Here we assess how this adventure can illuminate inorganic and catalytic chemistry. In particular X-ray inelastic scattering provides a means of exploiting X-ray free electron lasers, as a parallel to laser Raman spectroscopy
Men in Nursing: Implications for the Profession and Broader Workforce Trends
Typically,nursing has been considered a gendered profession dominated by women. As traditionally blue-collar, male-dominated occupations such as assembly-line work have declined,the percentage of men in the nursing profession has increased to 12%. This is not a recent phenomenon;a significant percentage of men served as nurses up through the 1800’s.
In this analysis of men serving in the nursing workforce, we begin with a historical review and then discuss implications for the nursing profession, e.g., recruitment,education,practice, retention,and culture, as well as implications for the broader labor market, e.g., compensation trends by industry and gende
