Lifelong hematopoiesis is sustained by crosstalk between hematopoietic stem and progenitor cells (HSPCs) and specialized bone marrow niches. Acute myeloid leukemia (AML) upends that balance, as leukemic blasts secrete factors that remodel the bone marrow into a self-reinforcing leukemic niche. The inflammatory secretome behind this compartmental adaptation accounts for a progressive decline in hematopoietic function that leads to diagnosis and persists through early treatment. Not surprisingly, the mediators of an acute inflammatory injury and HSPC suppression have attracted much attention in an effort to alleviate morbidity and improve outcomes. HSPCs typically recover during disease remission and re-expand in the bone marrow (BM), but little is known about potentially lasting consequences for stem cells and progenitors. We recently showed that AML-experienced HSPCs actively participate in the inflammatory process during leukemic progression. HSPCs are constituent components of the innate immune system, and elegant studies of infection and experimental inflammation over the past decade have described the generation of an adoptively transferable, innate immune memory. Building on this paradigm, we discuss the potential translational relevance of a durable legacy in AML-experienced HSPC.
PROBLEM TO BE SOLVED: To obtain the subject medicine having high wound healing effect by embedding leukocyte or bone marrow cell into a matrix or attaching leukocyte or bone marrow cell to the matrix. SOLUTION: This agent is obtained by separating leukocyte or bone marrow cell from blood, mixing the separated leukocyte or bone marrow cell with a matrix (preferably biodegradable collagen, chitin, fibrin, etc.) in solution state, gelatinizing the mixture, as necessary, culturing the resultant gel in a solution containing cytokine (e.g. γ-interferon), a cell growth factor or a stimulating agent (e.g. a cyclic peptide of the formula and obtained by culturing Streptomyces nobilis, preferably in an amount of 10<-16> to 10<-2> based on culture medium). The agent has activated leukocyte or bone marrow cell. Strong wound healing promoting effect is exhibited by bringing the agent into contact with the wound part.
BACKGROUND: Ileal pouch-anal anastomosis ('pouch surgery') provides a chance to avoid permanent ileostomy after proctocolectomy, but can be associated with poor outcomes. The relationship between hospital-level/surgeon factors (including volume) and outcomes after pouch surgery is of increasing interest given arguments for increasing centralization of these complex procedures. The aim of this systematic review was to appraise the literature describing the influence of hospital-level and surgeon factors on outcomes after pouch surgery for inflammatory bowel disease.
METHODS: A systematic review was performed of studies reporting outcomes after pouch surgery for inflammatory bowel disease. The MEDLINE (Ovid), Embase (Ovid), and Cochrane CENTRAL databases were searched (1978-2022). Data on outcomes, including mortality, morbidity, readmission, operative approach, reconstruction, postoperative parameters, and pouch-specific outcomes (failure), were extracted. Associations between hospital-level/surgeon factors and these outcomes were summarized. This systematic review was prospectively registered in PROSPERO, the international prospective register of systematic reviews (CRD42022352851).
RESULTS: A total of 29 studies, describing 41 344 patients who underwent a pouch procedure, were included; 3 studies demonstrated higher rates of pouch failure in lower-volume centres, 4 studies demonstrated higher reconstruction rates in higher-volume centres, 2 studies reported an inverse association between annual hospital pouch volume and readmission rates, and 4 studies reported a significant association between complication rates and surgeon experience.
CONCLUSION: This review summarizes the growing body of evidence that supports centralization of pouch surgery to specialist high-volume inflammatory bowel disease units. Centralization of this technically demanding surgery that requires dedicated perioperative medical and nursing support should facilitate improved patient outcomes and help train the next generation of pouch surgeons.
PURPOSE:To provide an extremely safe surfactant having high emulsifying power and used in a bathing agent, a waste oil treatment agent, cosmetics, a food compsn. or a drug compsn. and produce a capsule containing oil-soluble health food or medicines. CONSTITUTION:A surfactant compsn. is a mixture of polyglycerine fused ricinoleic ester and polyglycerine lauric ester and containing 15-60wt.% of polyglycerine fused ricinoleic ester. This surfactant compsn. is added to a bathing agent, a waste oil treatment agent, a cosmetic compsn., a food compsn. and a drug compsn. Further, a capsule is produced by encapsulating a mixture consisting the surfactant compsn. containing 15-60wt.% of polyglycerine fused ricinoleic ester and 50wt.% or more of oil-soluble health food or medicines.
Group B2 (placebo) (n=2) will receive three injections of 0.9% Sodium Chloride on days 0, 14 and 28, using the same standard chemoprophylactic regimen with CQ (10 mg/kg CQ base loading dose, followed by weekly dosing with 5 mg/kg CQ base), for 5 instead of 10 wks. But Group B2 will receive ER-AZ, 2g on the day of 1st placebo injection and monitored for parasitemia by qPCR. In case that all CQ+ER-AZ treated volunteers are parasite-free until Day 11 following 1st injection, it will indicate that ER-AZ effectively killed the parasites in the liver prior to the development of parasitemia. With demonstration of the effectiveness of ER-AZ, the 2nd and 3rd immunizations will be done under ER-AZ alone, otherwise CQ prophylaxis will be continued and ER-AZ will not be administered for 2nd and 3rd injections. Group B2 will undergo homologous CHMI with PfSPZ Challenge 10 weeks after last immunization.
Routine dose group: Every three weeks as a cycle. On the first day of each cycle, Gemcitabine 1000mg / m2, Cisplatin 75mg / m2, Carboplatin auc5 were injected intravenously, and Gemcitabine 1000mg / m2 and Cindilimab 200mg were injected intravenously on the eighth day. After 4 or 6 cycles of treatment, if there is no disease progression, continue to use Cindilimab 200mg every three weeks until the disease progresses.
PURPOSE:To obtain antibacterial agent, anti-inflammatory drug and external medicine for cutis containing 6-hydroxyluteolin having strong antibacterial activity, wide antibacterial spectrum, high safety and strong anti-inflammatory action. CONSTITUTION:The aimed antibacierial agent, anti-inflammatory drug and external medicine for cutis contain 6-hydroxyluteolin expressed by the formula as active ingredient. 6-hydroxyluteolin, as naturally derived, e.g. is obtained by extraction of leaf of Catalpa bignonioides in a form of glucoside and hydrolyzing with acid, or able to be obtained by synthesis of 3,6-dihydroxy-2,4- dimethoxyacetophenone, etc., as a raw material. Said 6-hydroxyluteolin exhibits remarkable histamine release-inhibiting action. Besides, said external medicine for cutis exhibits not only anti-inflammatory effect but also inhibition of pollution or microbism by microorganism in a case of coating on affected part of inflammation.
Day 1: One time administration, two drops. Day 3-7: Two time administration, two drops each time (12 hours apart). Total 9 times administration. 8 subjects randomized 6:2 to NTX-101 or placebo.
Knee arthroplasty is one of the most common orthopedic procedures. Patients may complain severe pain due to the surgical trauma and the prosthesis. Opioid agents are commonly used for analgesia management. However, opioids have adverse effects such as nausea, vomiting, sedation and respiratory depression. Peripheral nerve blocks such as femoral block, adductor canal block (ACB) may be performed to reduce opioid consumption and opioid-related side effects.

Selective blockade of the saphenous nerve in the adductor canal for knee surgery provides effective analgesia without quadriceps muscle weakness. This is an important advantage of ACB since it there is no motor blockade in the postoperative period. Blocking of the motor branches leads to delaying of the mobilization and it increases the patient's falling risk. ACB, targets the saphenous nerve and the vastus medialis branch which are the two largest sensorial nerves of the femoral nerve that innervates the knee. ACB blocks the articular branches of the obturator nerve at the same time. Since the ACB is performed at the distal site of thigh it does not target majority of the efferent branches of the quadriceps muscle, therefore the strength of this muscle may not be affected. ACB is usually performed with a volume of 10-30 ml and studies may be needed including different volumes to understand its effectiveness.

The aim of this study is to compare the different volumes (20 ml, 30 ml, and 40 ml) of US-guided ACB for postoperative analgesia management after total knee arthroplasty. The primary aim is to compare postoperative opioid consumption and the secondary aim is to evaluate postoperative pain scores (VAS), motor blockage, the first mobilization time, and adverse effects related with opioids (allergic reaction, nausea, vomiting).
Branched-chain amino acids (BCAAs) and aromatic AAs (AAAs) are associated with increased risk for type 2 diabetes in adults. Studies in youth show conflicting results. We hypothesized that an AA metabolomic signature can be defined to identify youth at risk for β-cell failure and the development of type 2 diabetes. We performed targeted AA metabolomics analysis on 127 adolescents (65 girls; 15.5 [SD ±1.9] years old, Tanner stage II-V) with normal weight or obesity across the spectrum of glycemia, with assessment of AA concentrations by mass spectrometry, at fasting, and steady state of a hyperinsulinemic-euglycemic clamp, with determination of insulin sensitivity (IS) per fat-free mass (FFM). We measured insulin secretion during a 2-h hyperglycemic clamp and calculated the disposition index per FFM (DIFFM), a measure of β-cell function. Our results showed that concentration of glycine (Gly) and the glutamine (Gln)-to-glutamate (Glu) ratio were lower, whereas BCAA, tyrosine, and lysine (Lys) concentrations were higher in the groups with obesity and dysglycemia compared with those with normal weight. Gly and Gln-to-Glu ratio were positively related to IS and DIFFM, with opposite relationships observed for BCAAs, AAAs, and Lys. We conclude that a metabolic signature of low Gly concentration and low Gln-to-Glu ratio, and elevated BCAAs, AAAs, and Lys concentrations may constitute a biomarker to identify youth at risk for β-cell failure.
Non-traumatic head and neck emergencies include several disease processes such as infectious, inflammatory, and malignant. Infections are among the most common pathological processes that affect the head and neck, and are particularly important due to their acute, severe, and potentially life-threatening nature. Radiologists need to be well acquainted with these entities because any delay or misdiagnosis can lead to significant morbidity and mortality. Having a general understanding of such diseases is crucial, their prevalence, clinical presentation, common causative pathogens, route of spread, potential complications, and multimodality radiological appearance. Furthermore, understanding the relevant anatomy of the region, including the various fascial planes and spaces, is essential for radiologists for accurate image interpretation and assessment of potential complications. Our aim is to review the most common severe infections affecting the head and neck as well as other rare but potentially life-threatening infections. We will also describe their imaging features while focusing on the anatomy of the regions involved and describing their potential complications and treatment options.
BACKGROUND: We present a case of a 29-year-old male patient without immunodeficiency who suffered from rapid osteonecrosis and tooth exfoliation resulting from herpes zoster (HZ) infection in the left maxillary branch of the trigeminal nerve. Various complications associated with shingles infections have been reported, cases of osteonecrosis and tooth exfoliation due to HZ infection among young people without immunodeficiency are rare. In this case, we focus on the particular manifestation of HZ infection.
CASE PRESENTATION: The patient presented with clusters of erythema and papules, along with non-hemorrhagic blisters on the left face and the loss of the left upper incisor. All lesions were localized to the left side of the face without exceeding the midline. After receiving antibacterial and antiviral treatment, successful control over the infection was achieved; however, he experienced the loss of all upper teeth on the left side except for the first and second upper left molars.
CONCLUSION: This case highlights that rapid osteonecrosis and tooth exfoliation may occur among young individuals without immunodeficiency after HZ infection. HZ infection of the face should be taken very seriously to obtain prompt treatment to prevent the rare complications of bone necrosis and tooth loss as much as possible.
Surgical site infections (SSI) represent the most common type of nosocomial infection amongst surgical patients. They cause morbidity and mortality.

Surgical Drains are commonly inserted at the end of many surgical procedures. In contrast to potential benefits, drains are also thought to potentially serve as a conduit of bacteria into the wound and hence may increase the risk of SSI. Patterns of use of drains vary widely across surgical disciplines and individual practices. There are no uniform guidelines and standards are often rather based on tradition than on evidence. The aim of this large prospective study was to examine the association of presence, duration, type, number and location of drains with the risk of SSI in a contemporary and multicentric cohort of general, orthopedic trauma and vascular surgery procedures.
Polycystic ovary syndrome (PCOS) is an endocrine disorder that affects 6-12% of reproductive-aged women within the general population. Currently, there is limited knowledge on the current lifestyles of women with PCOS and the psychosocial factors associated with PCOS.

The researchers plan to examine potential lifestyle differences and psychosocial factors between PCOS and healthy women. The Research Team is also interested in the relationships between biological markers and lifestyle endpoints in women with and without PCOS. Previous literature has shown there are biological marker differences between those with and without PCOS. By examining these relationships, researchers may further understand whether PCOS status is associated with lifestyle parameters.

To accomplish these objectives, 360 women (120 women with PCOS, 120 women without PCOS and with normal menstrual cycles, and 120 women without PCOS and with irregular menstrual cycles) will be included in this study. An equal number of lean and overweight/obese women will be recruited within each group based on body mass index (BMI; Lean = 18 - 24 kg/m2 and overweight/obese ≥ 25 kg/m2). Women will be included in the PCOS group if they have a confirmed PCOS diagnosis from their primary care provider. Participants will complete a food frequency questionnaire, a sleep questionnaire, and a physical activity questionnaire. A researcher may also provide participants with a waist-worn accelerometer to monitor physical activity and a wrist-worn accelerometer to monitor sleep for a week. Ultrasound scans of the ovaries will be assessed and the following metabolic parameters will be assessed: (1) 75-gram oral glucose tolerance test; (2) dual X-ray absorptiometry (DXA) scan; (3) vitals and anthropometry assessment to measure waist and hip circumference, height, weight, blood pressure, and heart rate; (4) fasting blood tests to detect androgens (i.e., total testosterone, androstenedione, free androgen index); and (5) an (optional) subcutaneous fat biopsy. Women with and without PCOS will also be asked to complete a questionnaire that will assess the psychosocial factors (e.g., health beliefs). This can be conducted online, in person, or through phone.
Participants will be ask to attend 4 laboratory sessions during which they will be asked to smoke their usual brand (UB) cigarettes and then one of three study cigarettes with low, medium and high levels of sugar in separate sessions using a within-subject design with conditions counterbalanced determined by a Latin square. In each session, smokers will be asked to smoke a cigarette in a standardized manner (10 puffs,30 second interval between puffs) and 1 hour later, ad libitum. Each of the sessions will be separated by at least 48 hours but not more than 5 days.
Stimulation of target cells using light, e.g., in vivo, is implemented using a variety of methods and devices. In one example, embodiments involve methods for stimulating target cells using a photosensitive protein that allows the target cells to be stimulated in response to light. In another specific example embodiment, target cells are stimulated using an implantable arrangement. The arrangement includes an electrical light-generation means for generating light and a biological portion. The biological portion has a photosensitive bio-molecular arrangement that responds to the generated light by stimulating target cells in vivo. Other aspects and embodiments are directed to systems and methods for screening chemicals based screening chemicals to identify their effects on cell membrane ion channels and pumps, and to systems and methods for controlling an action potential of neuron (e.g., in in vivo and in vitro environments).
Cholangiocarcinoma (CCA) is a cancer that easily invades adjacent structures. Vascular endothelial growth factor (VEGF) and VEGF receptor 2 (VEGFR2) are increased in most types of cancer and inhibit tumor progression by blocking VEGF/VEGFR2 \[16\]. Apatinib is a highly selective VEGFR2 antagonist that inhibits apoptosis and growth of CCA cells. Apatinib is also a derivative of PTK787, and its targets include VEGFR-1, VEGFR-2, PDGFR, c-kit, c-Src, etc. The activity of Apatinib against VEGFR-2 is 137 times that of PTK787, the IC50 is only 1nmol/L, and it can strongly inhibit tumor angiogenesis. At the same time, it can also inhibit the downstream signal transduction mediated by KDR and inhibit tumor growth.
Healthy volunteers will receive the placebo equivalent to RG7625 as oral capsules once or twice daily for 8 days. Each cohort will receive intradermal administration of 4 antigens (tetanus toxoid, tuberculin purified protein derivative \[PPD\], Candida albicans, and Trichophyton species) and a negative control at Screening and on Day 7 of treatment to assess for DTH.
This study aims to design and synthesize a series of novel formononetin (FMN) derivatives and explore their protective effects on oxygen glucose deprivation/relapse (OGD/R) damage to H9C2 cells, along with their molecular regulatory mechanisms. The OGD/R model was established to simulate myocardial ischemia-reperfusion injury. The protective effects of these novel compounds on H9C2 cells were evaluated using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) method, while the apoptosis rate, myocardial enzyme activity, and autophagy reaction post-compound treatment were assessed using kit-based methods. The formation of autophagosomes in H9C2 cells was observed via transmission electron microscopy, and the expression levels of autophagy-related proteins phosphatidylinositol 3-kinase (PI3K), Akt, Beclin-1, and P62 were determined using Western blotting. The experimental findings demonstrated that compounds 1-6 (C1-6) exhibited varying degrees of protective effects on damaged H9C2 cells, generally outperforming the parent compound FMN. Among these compounds, C4 demonstrated the most significant activity, even surpassing the positive control drug diltiazem. Further mechanistic investigations revealed that C4 could mitigate apoptosis rates, reduce the activity of myocardial enzyme (such as aspartate aminotransferase (AST), lactate dehydrogenase (LDH), and CK), diminish the number of autophagic vesicles, and restore excessive autophagy. Additionally, C4 exerted its protective effects by downregulating the expression of autophagic proteins PI3K, Akt, Beclin-1, P62, LC3 and ATG12. These results indicated that C4 regulates autophagy through the PI3K/Akt/Beclin-1 signaling pathway, thereby exerting a protective effect on cardiomyocytes. Therefore, C4 emerges as a potential myocardial protective drug, offering a new research direction and strategy for the treatment of myocardial ischemia-reperfusion injury.
