NADPH mimics the antidepressant effects of exercise in a chronic unpredictable stress rat model.

Exercise is known to be an effective intervention for depression. NADPH has been demonstrated to have neuroprotective effects in our previous studies. This study aimed to investigate if NADPH has antidepressant effects and can mimic the effects of exercise in a chronic unpredictable stress (CUS) rat model. CUS rats underwent an 8-week swimming exercise (30 min/d, 5d/w) or were intraperitoneally administered 4 mg/kg or 8 mg/kg NADPH. The open field test (OFT), sucrose preference test (SPT), novelty-suppressed feeding test (NSFT), and forced swimming test (FST) were used to examine the antidepressant-like behaviors of the rats. Exercise, 4 mg/kg, and 8 mg/kg NADPH similarly reduced anxiety, as demonstrated by the number of fecal pellets. Meanwhile, exercise and 8 mg/kg NADPH significantly increased locomotion activity in the OFT. Exercise, 4 mg/kg, and 8 mg/kg NADPH effectively reversed CUS-induced anhedonia in rats in the SPT. Exercise, 4 mg/kg, and 8 mg/kg NADPH had no impact on appetite of depressed rats; however, 8 mg/kg NADPH increased the rats' exploratory activity in the NSFT. Exercise, 4 mg/kg, and 8 mg/kg NADPH significantly reduced the immobility time of CUS model rats, while exercise and 8 mg/kg NADPH postponed the early CUS-induced "immobility" in the FST. These results demonstrated that NADPH has similar antidepressant-like effects to exercise in CUS-induced depression model rats and is a potential exercise-mimicking antidepressant.

Herpes simplex virus reactivation after nonablative fractional laser to treat facial photoaging.

Contemporary approaches for facial rejuvenation encompass the utilization of both ablative and nonablative laser techniques. Extensive research has elucidated the adverse consequences associated with ablative laser treatment, such as the emergence of infectious, follicular, scarring, and pigmentary alterations. Nonablative fractional lasers exhibit commendable cosmetic outcomes, characterized by a diminished incidence of complications owing to their photomechanical mechanisms, in contrast to ablative laser modalities. Nonetheless, it is imperative to acknowledge that untoward effects may still manifest. In this report, we present two cases of herpes simplex virus (HSV) reactivation subsequent to nonablative fractional resurfacing. Timely identification and the appropriate administration of antiviral agents are important, which serve as imperative measures to mitigate the long-term consequences that may arise in the event of complications.

Hypomethylation-associated LINC00987 downregulation induced lung adenocarcinoma progression by inhibiting the phosphorylation-mediated degradation of SND1.

DNA methylation, an epigenetic regulatory mechanism dictating gene transcription, plays a critical role in the occurrence and development of cancer. However, the molecular underpinnings of LINC00987 methylation in the regulation of lung adenocarcinoma (LUAD) remain elusive. This study investigated LINC00987 expression in LUAD patients through analysis of The Cancer Genome Atlas data sets. Quantitative real-time polymerase chain reaction (RT-qPCR) and fluorescence in situ hybridization assays were used to assess LINC00987 expression in LUAD. The bisulfite genomic sequence PCR (BSP) assay was used to determine the methylation levels of the LINC00987 promoter. The interaction between LINC00987 and SND1 was elucidated via immunoprecipitation and RNA pull-down assays. The functional significance of LINC00987 and SND1 in Calu-3 and NCI-H1688 cells was evaluated in vitro through CCK-8, EdU, Transwell, flow cytometry, and vasculogenic mimicry (VM) tube formation assays. LINC00987 expression decreased in LUAD concomitant with hypermethylation of the promoter region, while hypomethylation of the LINC00987 promoter in LUAD tissues correlated with tumor progression. Treatment with 5-Aza-CdR augmented LINC00987 expression and inhibited tumor growth. Mechanistically, LINC00987 overexpression impeded LUAD progression and VM through direct binding with SND1, thereby facilitating its phosphorylation and subsequent degradation. Additionally, overexpression of SND1 counteracted the adverse effects of LINC00987 downregulation on cell proliferation, apoptosis, cell migration, invasion, and VM in LUAD in vitro. In conclusion, this pioneering study focuses on the expression and function of LINC00987 and reveals that hypermethylation of the LINC00987 gene may contribute to LUAD progression. LINC00987 has emerged as a potential tumor suppressor gene in tumorigenesis through its binding with SND1 to facilitate its phosphorylation and subsequent degradation.

Treatment of periorbital aging with negative pressure fractional microneedle radiofrequency: A self-controlled clinical trial.

BACKGROUND: Several treatment modalities are used for the treatment of periorbital rejuvenation with variable results. Recent studies showed that fractional radiofrequency may be an effective treatment modality for periorbital aging. This study aims to determine the efficacy and safety of negative pressure fractional microneedle radiofrequency (NPFMR) as a treatment for periorbital aging. METHODS: Twenty-five patients with periorbital aging were involved in this study. They were treated two times with an interval of 1 month. The patients were evaluated before treatment and 1, 3, and 6 months after the final treatment. RESULTS: The research findings suggest that periorbital wrinkles of the patients were significantly improved by VISIA system (p < 0.05). Physiological indicators detected by MPA10 system showed that compared with before treatment, the hydration increased (p < 0.05) and trans epidermal water loss (TEWL) decreased (p < 0.05) at 3 and 6 months after treatment. The glossiness increased at 1 month after treatment compared to pre-treatment (p < 0.05) and returned to the baseline level at 3 and 6 months after treatment. There was no significant change in melanin content (p > 0.05). Periorbital dermal thickness of the patients significantly increased at 1, 3, and 6 months after treatment according to skin ultrasound (p < 0.05). A periorbital skin biopsy revealed that the collagen fibers in the dermis were significantly thicker and more orderly after treatment, and the expression of type I collagen fibers and elastic fibers was increased compared with that before treatment. One patient developed post-inflammatory hyperpigmentation (PIH) at 1 month after the first treatment, which improved after active treatment. No other adverse reactions were observed. CONCLUSIONS: NPMFR could be an effective and safe treatment modality for the treatment of periorbital aging.

Dietary cadmium health risk assessment for the Chinese population.

Cadmium (Cd) has high rates of soil-to-plant transference, coupled with its non-biodegradability and persistence; long-term management of Cd in agriculture is thus required to ensure better soil and food security and safety. Identifications of regions with high soil Cd concentration or high dietary Cd intakes are critical public health priorities. Human health risk assessment for dietary Cd intake was thus undertaken by employing three approaches: FCA (food chain approach), TDA (total diet approach), and FQA (food quality approach). The correlation between green/total vegetable consumption rates and dietary Cd intake from vegetables was statistically significant. For consumption, the hazard quotients (HQs) calculated by FCA and TDA were all less than 1 except for Hunan and Sichuan province. For rice consumption, the HQs derived by FCA or TDA approach for eight provinces exceeded 1. Residents in Hubei, Guangxi, Jilin, Zhejiang, Liaoning, Shanghai, Sichuan, and Guangxi were more vulnerable due to their notable higher consumption rates.Weighted rankings of the health risk levels were determined to derive the comparative risk management priority. For Cd intake from vegetables, four provinces/cities have high relative priority; for Cd intake from grains, three provinces have high relative priority. The comparative risk management priority for Hunan and Sichuan was high for dietary intake from vegetables or rice. Weighted average HQs were derived to determine the integrated dietary Cd intake health risk levels for dietary intake from vegetables or grains. The risk levels for Hunan, Guangxi, Sichuan, and Zhejiang are high, so effective measures should be taken to reduce Cd dietary intakes to ensure health protection.It is envisaged that the methodology employed in this study could provide useful insights into how various approaches can be integrated to determine human health risk levels for Cd intake, so more effective and targeted measures can be taken accordingly for the relevant regions.

Insights into the phylogeny of the family Deviatidae (Protozoa, Ciliophora, Hypotrichia) based on multi-gene, morphological and ontogenetic information, with the establishment of a new species Deviata multilineae n. sp.

Hitherto, the phylogeny of ciliated protists, an important group of model organisms in many fields, has been mainly based on a single marker gene (SSU rDNA, nuclear small subunit ribosomal RNA gene). However, there is increasing evidence showing this is insufficient to provide robust phylogenies and has resulted in confusing systematics in many ciliates groups. Among these, the phylogenies within family Deviatidae (Spirotrichea, Hypotrichia) are ambiguous due to the dependence on SSU rDNA and undersampling. Here, we provide eight new sequences and conduct phylogenetic analyses based on both multi-gene and single-gene to clarify evolutionary relationships among all deviatids for which gene sequence are available. The results reveal that: (1) the monophyly of Deviatidae is well-supported by both single-gene and concatenated data; (2) the presence of fine cirri and relatively wide spacing of these cirri within all rows are plesiomorphies of Deviatidae; (3) Pseudosincirra longicirrata is closely related to Deviata rositae, which is supported by their shared possession of dorsomarginal kineties; (4) phylogenetic analyses and approximately unbiased test based on multi-gene support a close relationship among taxa lacking dorsomarginal kineties (D. parabacilliformis, D. multilineae nov. spec., D. abbrevescens, D. brasiliensis and Perisincirra paucicirrata); (5) Deviatidae shows a close relationship with Dorsomarginalia and Strongylidium-Hemiamphisiella-Pseudouroleptus assemblage, suggesting the presence/absence of dorsomarginal kineties is phylogenetically informative in this family and presence of them may be a plesiomorphy. Based on the morphological, morphogenetic and phylogenetic data, the evolutionary relationships within Deviatidae are hypothesized, and a new ciliate, Deviata multilineae nov. spec., collected from China, is investigated.

Enteral Nutrition: Based on the Combination of Nutrison Fibre and TPF-DM with A Marine Biological-Based Active Polysaccharide Preparation.

Good nutrition is essential for human growth, wound healing, and spiritual vitality. However, some individuals are unable to eat or experience gastrointestinal problems such as severe diarrhea, vomiting, gastric retention, and even gastrointestinal bleeding for a variety of causes. Therefore, it has important clinical significance to provide patients with required nutrients and maintain the integrity of the body's tissues and organs through enteral nutrition. Based on this, this work uses a dual carrier of polylactic acid (PLA) and polyvinyl alcohol (PVA) to carry marine biopolysaccharides combined with sodium alginate (PSS) and successfully obtains the intestinal tract based on marine bioactive polysaccharides. Nutritional oral biological preparations (PSS-PLA/PVA) also cooperate with enteral nutritional suspension (diabetes) (TPF-DM) and Nutrison fibre to provide enteral nutritional support for critically ill patients. PSS-PLA/PVA has been shown in clinical studies to increase the effect of enteral nutrition support, the function of intestinal T lymphatic tissue, and the ability to control immunological function, indicating that it is worthy of further clinical development.

Morphology, cell division, and phylogeny of Notohymena antarctica Foissner, 1996 and Engelmanniella mobilis (Engelmann, 1862) Foissner, 1982 (Ciliophora, Hypotrichia).

The morphogenesis of two hypotrich ciliates, Notohymena antarctica Foissner, 1996 and Engelmanniella mobilis (Engelmann, 1862) Foissner, 1982, were investigated using protargol staining. The main events of the oxytrichid Notohymena antarctica during binary fission are as follows: (1) the oral primordium of the opisthe is formed apokinetally left of transverse cirrus II/1; (2) six streaks of frontal-ventral-transverse cirral anlagen are segmented in the ordinary pattern 1: 3: 3: 3: 4: 4 from left to right, which form three frontal, four frontoventral, one buccal, three ventral, two pretransverse ventral and five transverse cirri; (3) marginal anlagen are formed intrakinetally and the right marginal anlagen develop much earlier than those on the left. Phylogenetic analyses based on SSU rDNA sequence data indicate that Notohymena is monophyletic. A remarkable morphogenetic feature in E. mobilis is the mode of formation of the right marginal rows. In this paper, we clarified that the right marginal anlagen of E. mobilis are formed and develop to the right of the parental outer right marginal row, and that the grandparental (inner) right marginal row and great-grand parental (the outermost) left marginal row are resorbed. It is the first time to report a population of E. mobilis with comprehensive information, i.e. the morphology, ontogeny and molecular sequence.

A randomized, controlled, split-face study of botulinum toxin and broadband light for the treatment of erythematotelangiectatic rosacea.

To study the efficacy and safety of botulinum toxin (BTX) combined with broadband light (BBL) in the treatment of rosacea-related erythema and flushing. A randomized, single-blind, split-face controlled study including 22 patients with erythemato telangiectatic rosacea were enrolled. Both cheeks were randomly divided into experimental group and control group. They were treated three times with an interval of 1 month. In the first treatment, the experimental group received BBL treatment and intradermal injection of BTX, and the control group received BBL treatment and intradermal injection of the same amount of normal saline; in the second and third treatments were both groups received the same BBL treatment. The patients were evaluated before the first treatment and 1, 2, 3, and 6 months after the treatment. Compared with the control group, the hydration in the experimental group increased and the global flushing symptom score (GFSS), VISIA red value, erythema index, transepidermal water loss, and sebum secretion decreased. The differences were statistically significant (p < 0.05). In the experimental group, at 3 months after the first treatment, compared with before treatment, the GFSS, VISIA red value, erythema index, transepidermal water loss and sebum secretion decreased the hydration increased. The sebum secretion returned to the pretreatment level in 6 months after treatment, and the other indexes maintained the level in 3 months after treatment. One patient had a slight lifting limitation of the corners of his mouth after 10 days of BTX injection, without special treatment, and recovered after 1 month. BTX intradermal injection combined with BBL has a definite therapeutic effect on the improvement of rosacea related erythema and flushing, which is better than simple BBL, and has high safety. It is worthy of clinical promotion.

Redescription, Morphogenesis, and Molecular Phylogeny of Pseudosincirra longicirrata nov. comb., With Establishment of a New Genus Pseudosincirra nov. gen. (Ciliophora, Hypotrichia).

The morphology and morphogenesis of Pseudosincirra longicirrata nov. gen. and nov. comb., isolated from southern China, were investigated with living observation and protargol staining. Our population is similar to the original population in living characteristics and ciliary patterns. The main determinable morphogenetic features of P. longicirrata nov. comb. are the presence of five frontoventral-transverse cirral anlagen (FVT-anlagen) and a dorsomarginal kinety anlage. According to the origin of FVT-anlagen IV and V in proter, it can be determined that P. longicirrata nov. comb. possesses two frontoventral rows and one right marginal row. Hence, a new genus, Pseudosincirra nov. gen., is proposed, and the diagnosis of P. longicirrata nov. comb. is improved. The new genus is diagnosed as follows: adoral zone of membranelles and undulating membranes is in a Gonostomum pattern; there are three enlarged frontal cirri, one buccal cirrus, and one parabuccal cirrus; postperistomial cirrus and transverse cirri are lacking; there are two more or less long frontoventral rows and one right and two or more left marginal rows; cirri within all rows very widely spaced; dorsal kinety pattern is of Urosomoida type, that is, three dorsal kineties and one dorsomarginal kinety; and caudal cirri are present. Phylogenetic analyses based on the small subunit ribosomal (SSU rDNA) sequence data indicate that P. longicirrata nov. comb. clusters with Deviata and Perisincirra. It is considered that Pseudosincirra nov. gen. and Perisincirra paucicirrata should be assigned to the family Deviatidae; fine cirri, and cirri within all rows being relatively widely spaced, should be considered as plesiomorphies of Deviatidae; and Deviatidae is closely related to Dorsomarginalia or Strongylidium-Hemiamphisiella-Pseudouroleptus.

Accuracy of Various Forms of Contrast-Enhanced MRI for Diagnosing Hepatocellular Carcinoma: A Systematic Review and Meta-Analysis.

BACKGROUND: Contrast-enhanced MRI can be used to identify patients with hepatocellular carcinoma (HCC). However, studies around the world have found differing diagnostic accuracies for the technique. Hence, we designed this meta-analysis to assess the accuracy of contrast-enhanced MRI for HCC diagnosis. METHODS: We conducted a systematic search for all studies reporting the diagnostic accuracy of contrast-enhanced MRI for HCC in the databases of MEDLINE, EMBASE, Cochrane Library, Web of Science, SCOPUS, ScienceDirect, and Google Scholar from inception until January 2021. We used the "Midas" package from the STATA software to perform the meta-analysis. RESULTS: Our study was based on 21 publications with 5,361 patients. The pooled HCC diagnosis sensitivity and specificity were 75% (95% CI, 70%-80%) and 90% (95% CI, 88%-92%), respectively, for gadoxetic acid-enhanced MRI; and they were 70% (95% CI, 57%-81%) and 94% (95% CI, 85%-97%), respectively, for MRI with extracellular contrast agents (ECA-MRI). We found significant heterogeneity with a significant chi-square test and an I 2 statistic >75%. We also found significant publication bias as per Deeks' test results and funnel plot. CONCLUSION: We found that both types of contrast-enhanced MRI are accurate diagnostic and surveillance tools for HCC and offer high sensitivity and specificity. Further studies on different ethnic populations are required to strengthen our findings.

Application of the sheepskin mattress in clinical care for pressure relieving: a quantitative experimental evaluation.

This study aimed at quantitatively evaluating the effectiveness of sheepskin mattress (SSM) in pressure relieving, and then variables of peak pressure (mmHg) (PP), average pressure (AP) and contact area (cm(2)) (CA) at the total, back, sacrum and heel regions of 18 students supinely lying in a control mattress (CM), standard hospital mattress (SHM), SHM+SSM, SSM+CM and AM+CM were measured and contrasted. Paired-T test with a significant level of .05 shows that: the intervention of SSM significantly increased the total CA of SHM by 395.6 cm(2) and lowered its PP and AP by 8.8 and 2.0 mmHg respectively; further, the pressure distribution of SSM+CM was superior to that of AM+CM. The reliability of this study, with exception of the heel area, was proven to be good. Overall, the sheepskin mattress is an effective product in pressure reliving.
