    While the overall percentage of residents who withdraw (2.7%) or take extended leave (1.0%) are low, subgroup analysis has found that minority physicians are approximately 30% more likely to withdraw from residency than their white counterparts and 8 times more likely to take extended leave of absence. With ongoing national efforts to support diversity in medical education through increased recruitment of underrepresented in medicine (UiM) students to residency programs, there is paucity of data identifying specific experiences challenging or contributing to their overall resiliency. Better understanding of the lived experience of UiM residents will allow residency programs to create successful curricular programing and support structures for residents to thrive.

    We sought to understand UiM internal medicine residents’ experiences during residency training.

    We used a retrospective review of focus group transcripts of UiM internal medicine residents from 5 academic institutions in 2017 (4 in North Carolina and 1 in Georgia).

    Of 100 self-identified UiM residents from 5 institutions, 59 participated in the focus groups. Using a consensus-based review of transcripts, 25 distinct codes in 8 parent code categories were determined. Two primary themes emerged resilience and isolation. Three secondary themes-social support, mentorship, and external expectations and/or biases-served as mediators for the primary themes.

    UiM residents who became or were already resilient commonly experienced isolation at some time in their medical career, specifically during residency. Moreover, they could be influenced and positively or negatively affected by social support, mentorship, and external expectations and biases.

The varicocele testis is characterized by the presence of intracellular iron deposits that contribute to the associated oxidative stress. Therefore, we tested the hypothesis that administration of an iron-chelating agent, such as deferasirox (DFX), could potentially mitigate the consequences of varicocele on testicular tissue and spermatozoa. Using a well-established rat model of varicocele (VCL), we show that treatment with DFX partially improved the structure and function of the testis and spermatozoa. In particular, sperm motility was markedly restored whereas abnormal sperm morphology was only partially improved. No significant improvement in sperm count was observed that could be associated with the proapoptotic response observed following iron chelation treatment. No reduction in oxidative damage to spermatozoa was observed since lipid peroxidation and DNA integrity were not modified. This was suggested to be a result of increased oxidative stress. Finally, we also saw no indication of attenuation of the endoplasmic reticulum/unfolded protein (ER/UPR) stress response that we recently found associated with the VCL testis in rats.

    We tried to investigate whether electroacupuncture (EA) can reduce inflammation of dry eye disease (DED) by regulating

    7nAChR and inhibiting the NF-

    B signaling pathway.

    Healthy New Zealand white rabbits were treated with scopolamine hydrobromide (Scop) for 21 consecutive days to establish the DED animal model. After 21 days, EA, fluorometholone (Flu), and

    7nAChR antagonist (

    -BGT) treatments were performed, and the Scop injection was continued until day 35. During treatment, the fluorescence staining of the corneal epithelium and the level of tear flow were observed. The influence of EA on the LG pathology and inflammatory factors ACh,

    7nAChR, and NF-

    B was detected using the LG histopathology, transmission electron microscopy (TEM), cytokine protein chip technology, enzyme-linked immunosorbent assay (ELISA), and Western blot.

    The EA stimulation can reduce the corneal epithelial damage and repair epithelial cell ultrastructure, promote the tear secretion, relieve the LG atrophy and decrease li. This expression indicates that the

    7nAChR/NF-

    B signaling pathway may serve as a potential therapeutic target for EA to treat DEDs.

    These results prove that EA can alleviate DEDs by stimulating the acupoints around the eyes. These beneficial effects are related to the upregulation of α7nAChR and the downregulation of NF-κB in the LG. The protective effect of LG is mediated through the anti-inflammatory pathway mediated by α7nAChR. EA can reduce the NF-κB P65 nuclear transcription and reduce inflammatory factors by regulating α7nAChR. selleck This expression indicates that the α7nAChR/NF-κB signaling pathway may serve as a potential therapeutic target for EA to treat DEDs.Cerebral stroke is a serious worldwide health problem, as can be seen by the global epidemic of the disease. In this disorder, when the blood flow is compromised by ruptures or blocked arteries, sudden death of neurons is observed as a result of a lack of oxygen and nutrients. Numerous severe problems and frequent complications also exist in stroke patients; therefore, there is an urgent need to develop new therapeutic, diagnostic, and prognostic methods for the disease. At present, the diagnosis of stroke is based on a neurological examination, medical history, and neuroimaging, due to the fact that rapid and noninvasive diagnostic tests are unavailable. Nevertheless, oxidative stress and inflammation are considered key factors in stroke pathogenesis. Oxygen free radicals are responsible for oxidation of lipids, proteins, and DNA/RNA, which in turn contributes to oxidative damage of the brain. Toxic products of the oxidation reactions act cytostatically on the cell by damaging cell membranes and leading to neuronal death by apoptosis or necrosis. Thus, it seems that redox/inflammatory biomarkers might be used in the diagnosis of the disease. Nowadays, saliva is of increasing interest in clinical laboratory medicine. Redox biomarkers could be obtained easily, noninvasively, cheaply, and stress-free from saliva. This minireview is aimed at presenting the current knowledge concerning the use of salivary biomarkers of oxidative stress and inflammation in the diagnosis and prognosis of stroke.
