Despite publishing and securing research grants being obligatory in research universities, the literature on the factors influencing academic productivity is relatively scarce. Thus, in this study, we aimed to determine the personal and behavioural-related factors that influence the culture of publishing and securing research grants among academicians with lower research-related performance. This cross-sectional study was conducted among 49 academic staff members of Universiti Kebangsaan Malaysia (UKM). A self-administered questionnaire consisting of personal, attitude and behavioural (barriers, perceived stress scale, work extrinsic and intrinsic motivation scale, psychological well-being scale, and basic needs satisfaction scale) questions were distributed during a workshop and online. Simple linear regression (SLR) analyses were performed for each variable, followed by multiple linear regression (MLR) to identify the associated factors of research output. After adjusting for covariates, having a doctoral degree (β=0.396, 95% CI=0.221-2.146, p<0.05) and integrated regulation (β=0.574, 95% CI=0.036-3.612, p<0.05) were found to be associated with research grant acquisition (R2=0.273). Moreover, increasing age (β=0.426, 95% CI=0.088-0.397, p<0.05), living alone (β=0.331, 95% CI=0.944-6.626, p<0.05), having a doctoral degree (β=0.248, 95% CI=0.174-6.747, p<0.05), environmental mastery (β=0.318, 95% CI=0.013-0.347, p<0.05), self-acceptance (β=0.284, 95% CI=0.010-0.242, p<0.05), satisfaction incompetence (β=0.273, 95% CI=0.001-0.200, p<0.05) and relatedness (β=0.280, 95% CI=0.001-0.116, p<0.05) were found to be the factors that influence the publications produced among participants (R2 =0.423). The findings of this study could be used by management to formulate effective strategies to increase the productivity of academics in their research-related performance.

BACKGROUND: Osteoporosis, characterized by decreased bone mineral density due to an imbalance between osteoblast and osteoclast activity, poses significant challenges in bone healing, particularly in postmenopausal women. Current treatments, such as bisphosphonates, are effective but associated with adverse effects like medication-related osteonecrosis of the jaw, necessitating safer alternatives. METHODS: This study investigated the use of L-serine-incorporated gelatin sponges for bone regeneration in calvarial defects in an ovariectomized rat model of osteoporosis. Thirty rats were divided into three groups: a control group, a group treated with a gelatin sponge containing an amino acid mixture, and a group treated with a gelatin sponge containing L-serine. Bone regeneration was assessed using micro-computed tomography (micro-CT) and histological analyses. RESULTS: The L-serine group showed a significant increase in bone volume (BV) and bone area compared to the control and amino acid groups. The bone volume to total volume (BV/TV) ratio was also significantly higher in the L-serine group.Immunohistochemical analysis demonstrated that L-serine treatment suppressed the expression of cathepsin K, a marker of osteoclast activity, while increasing serine racemase activity. CONCLUSION These findings suggest that L-serine-incorporated gelatin sponges not only enhance bone formation but also inhibit osteoclast-mediated bone resorption, providing a promising and safer alternative to current therapies for osteoporosis-related bone defects. Further research is needed to explore its clinical applications in human patients.

Estrogen, through binding to its receptors in the female endometrium, promotes the proliferation, differentiation, and angiogenesis of endometrial stromal cells, thereby playing a critical role in endometrial injury repair, regeneration, and the prevention and treatment of intrauterine adhesions. Currently, various estrogen-based pharmaceutical formulations are applied in clinical practice, and the development of related products is progressively advancing. This review systematically outlines the etiology of endometrial injury and the mechanisms by which estrogen facilitates endometrial repair and regeneration. Furthermore, it highlights recent research progress and clinical applications of estrogen-based therapies in endometrial regeneration, aiming to provide a valuable reference for relevant scientific research and clinical practice.

Objective:To analyze the clinical features of patients with traumatic optic neuropathy (TON) and to explore its clinical patterns and treatment outcomes.Methods:A retrospective analysis was conducted on data from 323 patients (334 eyes) with TON, who were treated in the Department of Otorhinolaryngology Head and Neck Surgery, the Affiliated Hospital of Qingdao University from April 1999 to October 2024. Among these patients, 288 were male and 35 were female, with ages ranging from 4 to 70 years. All patients were followed up for a period of 6 to 24 months, with the final follow-up visual acuity recorded as the ultimate visual outcome. The visual acuity evaluation criteria were classified into five levels: no light perception, light perception, hand movement in front of the eye, counting fingers at 1 meter, and "chart-visible acuity". A treatment outcome was deemed effective if the post-treatment visual acuity improved by one level or more compared to pre-treatment, or if the chart-visible acuity improved by two lines or more on the logMAR chart. The clinical characteristics of patients, causes of injury, complications, treatment methods, and changes in visual acuity before and after treatment were summarized. Logistic regression analyses were performed to identify the influencing factors affecting treatment efficacy.Results:TON occurred mostly in young (215/323, 66.56%) males (288/323, 89.16%), the majority of patients came from villages and towns (236/323, 73.07%). Traffic accidents (232/323, 71.83%) remained the main etiology. Most patients had craniofacial injuries and other bodily injuries. The effective rate of vision improvement was 50.30% (168/334). Multiple logistic regression analyses identified that residual vision (light perception or better) at presentation ( OR=3.26, P<0.001) and receiving treatment within 7 days after injury ( OR=2.04, P=0.008) were protective factors on visual acuity recovery, while the presence of orbital wall fracture was a risk factor for visual acuity recovery ( OR=0.26, P<0.001). Additionally, undergoing surgical treatment was a protective factor for visual improvement in patients with no light perception ( OR=2.94, P=0.007). For patients with residual vision at presentation, orbital wall fracture was a significant risk factor ( OR=0.28, P=0.009). Conclusions:TON is more prevalent in young males and is primarily caused by traffic accidents, leading to a poor prognosis. Timely medical intervention following injury significantly influences prognostic outcomes. Early surgical intervention (within 7 days) is recommended, particularly for patients with no light perception at presentation.

ObjectiveThe study aims to investigate the intervention effect of modified Xiangsha Liujunzitang （M-XSLJZ） on intestinal-derived lipopolysaccharide （LPS）-activated Kupffer cell inflammation in rats with hyperlipidemia spleen deficiency syndrome. MethodsSeventy male SD rats were randomly divided into seven groups （n=10）： blank control （CON）， high-fat diet without spleen deficiency （HFD）， high-fat diet with spleen deficiency （SD-HFD）， M-XSLJZ low-， medium-， and high-dose groups （XS-L， XS-M， XS-H）， and western medicine control （R）. Spleen deficiency was induced in SD-HFD， XS-L， XS-M， XS-H， and R groups via irregular diet combined with exhaustive swimming for 15 days. The CON group received a standard diet， while other groups were fed a high-fat diet for 10 weeks to establish the hyperlipidemia model. After successful modeling， rats were treated for 8 weeks： M-XSLJZ was administered at 3.51， 7.02， 14.04 g·kg^-1 in XS-L， XS-M， and XS-H groups， respectively. The R group received 9×10^-4 g·kg^-1 of a reference drug. D-xylose excretion rate was measured by the phloroglucinol method. Blood lipids were assessed using an automated biochemical analyzer. Hematoxylin-eosin （HE） staining was used to evaluate the pathological conditions of the liver， and oil red O staining was used to observe the lipid deposition in the liver. The levels of LPS， portal vein serum LPS， LPS-binding protein （LBP）， serum interleukin-6 （IL-6）， IL-1β， and tumor necrosis factor-α （TNF-α） were detected by enzyme-linked immunosorbent assay （ELISA）. Immunofluorescence was used to evaluate CD86 expression and CD68/TLR4 co-localization in the liver. Protein levels of TLR4， MyD88， NF-κB p65， and p-NF-κB p65 in Kupffer cells were analyzed via Western blot automated protein analysis. Hepatic IL-6， TNF-α， and IL-1β mRNA and protein levels were measured using Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） and Western blot. ResultsCompared with the CON group， the SD-HFD group showed a decrease in D-xylose excretion （P<0.01）. TC， TG， HDL-C， and LDL-C increased （P<0.05， P<0.01）. A large number of hepatic lipid vacuoles and orange-red lipid droplet deposition appeared in the liver. Ileal LPS， portal LPS， and LBP increased （P<0.05， P<0.01）. The levels of serum IL-6， TNF-α， and IL-1β increased （P<0.01）. The expression of CD86 was upregulated （P<0.01）， and the co-expression of CD68 and TLR4 was enhanced. The protein levels of TLR4， MyD88， and p-p65 in Kupffer cells increased （P<0.01）. The mRNA and protein levels of IL-6， TNF-α， and IL-1β increased （P<0.05， P<0.01）. Compared with the HFD group， the SD-HFD group exhibited decreased D-xylose excretion （P<0.01）， higher HDL-C， LDL-C （P<0.05）， increased portal LBP and LPS （P<0.05）， increased serum IL-6 and TNF-α （P<0.01）， upregulated CD86 （P<0.01）， enhanced CD68/TLR4 co-expression， and higher TNF-α mRNA/protein （P<0.05）. Compared with the SD-HFD group， all M-XSLJZ treatment groups showed reduced TC， TG， and LDL-C （P<0.05， P<0.01）. XS-H and R groups displayed improved hepatic lipid deposition. XS-H and R groups had lower ileal LPS， portal LPS， and LBP levels （P<0.05， P<0.01）. All M-XSLJZ treatment groups exhibited reduced serum IL-6， IL-1β， and TNF-α （P<0.01）. The XS-H group showed downregulated CD86 （P<0.01） and weakened CD68/TLR4 co-expression. The XS-H group had reduced TLR4， MyD88， and p-NF-κB p65 in Kupffer cells （P<0.01）. XS-H and R groups showed lower IL-6， TNF-α， and IL-1β mRNA/protein （P<0.05， P<0.01）. ConclusionM-XSLJZ may exert its lipid-lowering effects by inhibiting intestinal-derived LPS and alleviating Kupffer cell inflammation in the liver.
