    The corneal endothelium (CE) is vital for the cornea to maintain its transparency. However, CE dysfunction occurs due to aging, intraocular surgery, trauma, dystrophy, etc. Corneal transplantation is the only method to clinically treat CE dysfunction; however, this treatment strategy faces the disadvantages of a global cornea shortage, graft failure, and severe side effects. There is a recognized need for a substitute for the CE. Stem cells are becoming increasingly common for the treatment of human diseases. In fact, several studies have documented the induction of corneal endothelial-like cells (CECs) from stem cells, but an ideal procedure has not yet been established. Thus, this study aimed at exploring a more efficient and robust differentiation method. We used a modified approach to differentiate induced pluripotent stem cells (iPSCs) into CECs. After the identification of differentiated CECs, the CECs were injected into the anterior chambers of the eyes of a rabbit model of bullous keratopathy. The rabbits were maintained in the eye-down position to ensure that the cells attached to the cornea. The results showed that corneal edema was alleviated in the rabbits injected with CECs compared with that in the rabbits belonging to the control group. This study extends the ability to differentiate iPSCs into CECs and provides a potential strategy for the treatment of reduced visual acuity caused by CE deficiency in the future.

    The aims of this study were to evaluate the prevalence of demoralization in a sample of end-of-life cancer patients’ family caregivers and investigate the association between demoralization and different factors, such as distress, hope, quality of life, and caregiver burden.

    The study used a cross-sectional design and 142 participants were sampled. Family caregivers were included if they were caring for a cancer patient in palliative care with a limited life expectancy.Socio-demographic data were gathered, and Italian versions of the following scales were administered Demoralization Scale (DS), Herth Hope Index (HHI), Caregiver Reaction Assessment (CRA), Short Form-36 Health Survey (SF-36), and Distress Thermometer (DT).

    The average total demoralization score was 29.04 (SD = 13.62). buy IKK-16 19.50% of caregivers was the low scorers at DS (0-25th percentile), 27.50% was the middle scorers (25th-75th percentile), and 39.00% was the high scorers (75th-100 percentile). 19.50% of the caregivers showed mild demoralization, 27.50% moderate demoralization, and 39.00% showed severe demoralization. Strong Moderate correlations were found between the total DS score and the

    HHI subscale (ρ = .520); the HHI total score (ρ = .528); the

    (ρ = .536) and

    (ρ = .675) SF-36 subscales. The HHI total score and the

    SF-36 subscale emerged as the main predictors of demoralization.

    The results show that not only end-of-life patients but also family caregivers may experience demoralization. This demoralization seems to be more associated to spiritual and psychological suffering rather than difficulties relating to caregivers’ personal time, social roles, physical states, and financial resources.

SH-SY5Y cells were treated with Aβ 1-42 to construct AD cell models. APP/PS1 mice were used for the animal experiments.  MiR-130a-3p was downregulated in Aβ-induced SH-SY5Y cells. Overexpression of miR-130a-3p attenuates Aβ induced SH-SY5Y cell apoptosis. Low miR-130a-3p expression was detected in the hippocampus tissues of AD mice. The Morris water maze (MWM) results indicated that miR-130a-3p upregulation reduced the escape latency time and increased the time of AD mice spent in the target quadrant. DAPK1 was the target gene of miR-130a-3p. High DAPK1 mRNA level was detected in Aβ treated PC 12 cells and in the hippocampus tissues of AD mice. It was concluded that overexpression of miR-130a-3p may attenuate Aβ-induced neurotoxicity and improve the cognitive function of AD mice via targeting DAPK1.Significance Nonhealing wounds are an ever-growing global pandemic, with mortality rates and management costs exceeding many common cancers. Although our understanding of the molecular and cellular factors driving wound healing continues to grow, standards for diagnosing and evaluating wounds remain largely subjective and experiential, whereas therapeutic strategies fail to consistently achieve closure and clinicians are challenged to deliver individualized care protocols. There is a need to apply precision medicine practices to wound care by developing evidence-based approaches, which are predictive, prescriptive, and personalized. Recent Advances Recent developments in “advanced” wound diagnostics, namely biomarkers (proteases, acute phase reactants, volatile emissions, and more) and imaging systems (ultrasound, autofluorescence, spectral imaging, and optical coherence tomography), have begun to revolutionize our understanding of the molecular wound landscape and usher in a modern age of therapeutic strategies. Herein, biomarkers and imaging systems with the greatest evidence to support their potential clinical utility are reviewed. Critical Issues Although many potential biomarkers have been identified and several imaging systems have been or are being developed, more high-quality randomized controlled trials are necessary to elucidate the currently questionable role that these tools are playing in altering healing dynamics or predicting wound closure within the clinical setting. Future Directions The literature supports the need for the development of effective point-of-care wound assessment tools, such as a platform diagnostic array that is capable of measuring multiple biomarkers at once. These, along with advances in telemedicine, synthetic biology, and “smart” wearables, will pave the way for the transformation of wound care into a precision medicine.
