The present invention describes a method which outlines a process for conversion of CBD to a Δ9-tetrahydrocannabinol (Δ9-THC) compound or derivative thereof involving treating a naturally produced CBD intermediate compound with an organoaluminum-based Lewis acid catalyst, under conditions effective to produce the Δ9-tetrahydrocannabinol compound or derivative thereof at a relatively high concentration. The source of the CBD is from industrial hemp having less than 0.3% Δ9-THC and extracting and purifying a CBD distillate or isolate or a combination thereof. This procedure will produce Δ9-THC that is essentially free from any other cannabinoids other than some trace amounts of the initial CBD starting material, or about 95% Δ9-THC and 2-4% CBD. Another aspect of the present invention relates to a process for further purification and enrichment of the Δ9-THC using distillation and collecting an essentially pure fraction of Δ9-THC using additional distillation or enrichment form of purification. Included are methods and processes to scale the reaction from the lab to large scale manufacturing. Included are methods for adding a molecule marker to authenticate high purity Δ9-THC products. Formulations and uses for pharmaceuticals, nutraceuticals, food products, and topicals are also provided.
Provided are methods and compositions for the repair of articular cartilage defects in a mammal. Denuded chondrogenic cells are proliferated ex vivo as monolayer cultures in order to expand the pool of available chondrogenic cells. During proliferation the chondrogenic cells stop secreting the extracellular matrix components, type II collagen and sulfated proteoglycans. The proliferated cells then are seeded into a pre-shaped well having a cell contacting, cell abhesive surface. The cells cultured in the well redifferentiate and begin to secrete cartilage-specific extracellular matrix again. Accordingly, essentially unlimited amounts of synthetic cartilage may be prepared from small samples of biopsy tissue. Also provided are methods for surgically repairing articular cartilage defects in mammals using the synthetic cartilage prepared in accordance with the invention.
Fluticasone/salmeterol study medication kit will contain an inhaler in the manufacturer's device. Patients will be instructed to inhale their medication twice a day for 12 weeks.
This study was to explore the mechanism of ferroptosis and hypoxic-ischemic brain damage in neonatal rats. The neonatal rat hypoxic-ischemic brain damage (HIBD) model was established using the Rice-Vannucci method and treated with the ferroptosis inhibitor liproxstatin-1. Cognitive assessment was performed through absentee field experiments to confirm the successful establishment of the model. Brain tissue damage was evaluated by comparing regional cerebral blood flow and quantifying tissue staining. Neuronal cell morphological changes in the rats' cortical and hippocampal regions were observed using HE and Nissl staining. ELISA was performed to determine GPX4, GSH and ROS expression levels in the rats' brain tissues, and Western blotting to assess the expression levels of 4-HNE, GPX4, GSS, ACSL4, SLC7A11, SLC3A2, TFRC, FHC, FLC, HIF-1α, and Nrf2 proteins in rat brain tissues. Compared to the Sham group, the HIBD group exhibited a significant decrease in cerebral blood perfusion, reduced brain nerve cells, and disordered cell arrangement. The use of the ferroptosis inhibitor effectively improved brain tissue damage and preserved the shape and structure of nerve cells. The oxidative stress products ROS and 4-HNE in the brain tissue of the HIBD group increased significantly, while the expression of antioxidant indicators GPX4, GSH, SLC7A11, and GSS decreased significantly. Furthermore, the expression of iron metabolism-related proteins TFRC, FHC, and FLC increased significantly, whereas the expression of the ferroptosis-related transcription factors HIF-1α and Nrf2 decreased significantly. Treatment with liproxstatin-1 exhibited therapeutic effects on HIBD and downregulated tissue ferroptosis levels. This study shows the involvement of ferroptosis in hypoxic-ischemic brain damage in neonatal rats through the System Xc--GSH-GPX4 functional axis and iron metabolism pathway, with the HIF-1α and Nrf2 transcription factors identified as the regulators of ferroptosis involved in the HIBD process in neonatal rats.

Circulating biomarkers are promising tools for early diagnosis of pathologies associated with aging. Inflammation and immunity are associated with the risk of sarcopenia and frailty in elderly patients. The investigators investigate the effect of an adapted physical activity program on the metabolism and function of circulating immune cells and miRNA in frail and non-frail elderly subjects. The main objective is to establish the link between biological markers of aging (immune cells phenotypes and function, miRNA) and motor capacities alteration/improvement. The secondary objectives are: (1) to characterize the functional and immunometabolic dimensions of frailty from objective indicators; (2) to propose a management system through adapted and individualized physical activity, based on objective indicators; (3) to evaluate the clinical impact of both frailty and its preventative management through physical activity; and (4) to identified new biomarkers of frailty. A total of 100 patients categorized as frail, pre-frail, and non-frail after a standardized geriatric evaluation are included in a comparative and interventional study. Exercise intervention consists in a 12-weeks physical activity program. Blood sample and physical/psychological functional measurements are performed before and after the 12-weeks physical activity program. ANOVA tests and correlational analysis will be performed. The finality of the study is to improve the medical prescription of physical activities in elderly patients.
OBJECTIVE: There has been an increase of attention and awareness of smell and taste loss due to the impact of COVID-19. However, little is known about the influence of COVID-19 on the number of psychophysical tests performed, the timing of these tests, or the protection protocols employed to protect against virus transmission. This study aimed to explore the changes in examination approaches, types of tests employed, and safety measures adopted by clinicians before and after the COVID-19 pandemic.
METHODS: A survey was distributed to 404 institutes of the Oto-Rhino Laryngological Society of Japan, consisting of otolaryngologists working in university hospitals, general hospitals, and private clinics. The anonymous online survey contained questions related to safety measures and chemosensory assessments performed before and after the COVID-19 pandemic. Specifically, participants were queried on the number and types of examinations conducted, the type of examiners who performed them, the timing of tests in suspected and non-suspected COVID-19 cases, modifications made due to the pandemic, and the protective measures adopted during chemosensory examinations.
RESULTS: Of the 201 respondents, representing a 50 % response rate, 49 % were from general hospitals, 48 % from university hospitals, and 3 % from private clinics. The study found a slight decrease in the overall number of chemosensory tests conducted post-COVID-19. In terms of who performed the test, there were no differences pre- and post- COVID-19. Most examinations (52-68 %) for suspected COVID-19 cases were performed 1-2 months after the onset of symptoms. Modifications in testing rooms and personal protective equipment (PPE) were reported by the majority of institutions post-pandemic. While different examination rooms or PPE were not commonly used based on a patient's previous COVID-19 diagnosis, changes were observed in testing practices. Most examinations were conducted in rooms with windows or fans, and PPE usage was high; surgical masks, eye visors or face shields, and disposable gloves being commonly used. Virus transmission from patient to examiner was reported in only one case during T&T olfactometer examination.
CONCLUSION: We investigated the impact of the COVID-19 pandemic on the number of olfactory and gustatory tests performed, the type of examiner, the examination room, and the use of PPE and found no significant difference before and after the COVID-19 pandemic on these factors. Adherence to a protection protocol involving the proper use of PPE in controlled environments enabled the continuation of olfactory and gustatory tests during the pandemic.
The recommended initial dose of pilocarpine hydrochloride tablets is 5 mg taken three times a day. Dosage should be titrated according to therapeutic response and tolerability. The usual dosage range is 15-30 mg per day. (Not to exceed 10 mg per dose.) Although early improvement may be realized, at least 12 weeks of uninterrupted therapy with pilocarpine hydrochloride tablets may be necessary to assess whether a beneficial response will be achieved. The incidence of the most common adverse events increases with dose. The lowest dose that is tolerated and effective should be used for maintenance.
Phase I/II, multi-center, prospective, blinded 2arm, parallel design and randomized controlled study. Three subjects will be treated with the investigational arm and will service as training cases. The next 2 randomized intervention cases will be staggered by 48-96 hours and observed for adverse events. Randomized enrollment will then be initiated for all participating sites. Assessment of subjects with Ortho-R/PRP combination with be compared to subjects not randomized to Ortho-R/PRP group receiving standard of care who undergo rotator cuff repair surgery. Patients will be assessed by collecting patient-reported outcomes, MRI, incidence of rotator cuff re-tears, hematology and all adverse events. Data from pre-operative evaluation, day of surgery, and post-operative at 10 days, and 1,3, 6 and 12 months will be collected.
With oral dosing, the onset of diuresis occurs within 1 hour and the peak effect occurs during the first or second hour and diuresis lasts about 6 to 8 hours. In healthy subjects given single doses, the dose-response relationship for sodium excretion is linear over the dose range of 2.5 mg to 20 mg. The increase in potassium excretion is negligible after a single dose of up to 10 mg and only slight (5 mEq to 15 mEq) after a single dose of 20 mg.

Edema

Torsemide has been studied in controlled trials in patients with New York Heart Association Class II to Class IV heart failure. Patients who received 10 mg to 20 mg of daily torsemide in these studies achieved significantly greater reductions in weight and edema than did patients who received placebo.

Hypertension

In patients with essential hypertension, torsemide has been shown in controlled studies to lower blood pressure when administered once a day at doses of 5 mg to 10 mg. The antihypertensive effect is near maximal after 4 to 6 weeks of treatment, but it may continue to increase for up to 12 weeks. Systolic and diastolic supine and standing blood pressures are all reduced. There is no significant orthostatic effect, and there is only a minimal peak-trough difference in blood pressure reduction.

The antihypertensive effects of torsemide are, like those of other diuretics, on the average greater in black patients (a low-renin population) than in nonblack patients.

When torsemide is first administered, daily urinary sodium excretion increases for at least a week. With chronic administration, however, daily sodium loss comes into balance with dietary sodium intake. If the administration of torsemide is suddenly stopped, blood pressure returns to pretreatment levels over several days, without overshoot.

Torsemide has been administered together with β-adrenergic blocking agents, ACE inhibitors, and calcium-channel blockers. Adverse drug interactions have not been observed, and special dosage adjustment has not been necessary.
The purpose of this study was (1) to determine the utility of shear wave elastography as a predictor for the mechanical failure of superficial knee ligaments and (2) to determine the viability of shear wave elastography to assess injury risk potential. Our hypothesis was that shear wave elastography measurements of the anterolateral ligament and medial collateral ligament would directly correlate with the material properties and the mechanical failure of the ligament, serving as a prognostic measurement for injury risk. 8 cadaveric specimens were acquired, and tissue stiffness for the anterolateral ligament and medial collateral ligament were evaluated with shear wave elastography. The anterolateral ligament and medial collateral ligament were dissected and isolated for unilateral mechanical failure testing. Ultimate failure testing was performed at 100 % strain per second after 50 cycles of 3 % strain viscoelastic conditioning. Each specimen was assessed for load, displacement, and surface strain throughout failure testing. Rate of force, rate of strain development, and Young's modulus were calculated from these variables. Shear wave elastography stiffness for the anterolateral ligament correlated with mean longitudinal anterolateral ligament strain at failure (R2 = 0.853; P<0.05). Medial collateral ligament shear wave elastography calculated modulus was significantly greater than the anterolateral ligament shear wave elastography calculated modulus. Shear wave elastography currently offers limited reliability in the prediction of mechanical performance of superficial knee ligaments. The utility of shear wave elastography assessment for injury risk potential remains undetermined.
The 170 kDa adhesin subunit of the Entamoeba histolytica Gal/GalNAc adherence lectin is encoded by members of a gene family that includes hgl1, hgl2 and a newly discovered gene, hgl3. The DNA and encoded protein sequences of the hgl genes are disclosed. A number of proteins and peptide fragments of the adhesin as well as other functional derivatives, preferably produced by recombinant methods in prokaryotic cells are disclosed. A preferred peptide for a vaccine composition corresponds to amino acids 896-998 of the mature 170 kDa lectin and contains the galactose- and N-acetylgalactosamine-binding activity of the native lectin. These compositions are useful as immunogenic vaccine components and as diagnostic reagents. Methods are provided for a vaccine comprising one or more peptides of the lectin to immunize subjects at risk for infection by E. histolytica. Additionally, immunoassay methods are disclosed for measuring antibodies specific for an epitope of the lectin. These methods detect E. histolytica-specific antibodies, some of which are specific for epitopes characteristic of pathogenic strains, nonpathogenic strains, or both.

The gut microbiota and the host maintain a conjoint relationship and together achieve optimal physiology via a multitude of interactive signalling cues. Dietary-derived L-tryptophan (L-trp) is enzymatically metabolized by the resident symbiotic gut microbiota to indole and various indole derivatives. Indole and indole metabolites secreted by the gut bacteria act locally in the intestinal cells as well as distally and modulate tissue-specific functions which are beneficial to the host. Functions attributed to these microbial indole metabolites in the host include regulation of intestinal permeability, immunity and mucosal roles, inflammation, and insulin sensitivity. On the other hand, dysregulation of gut microbiota L-trp metabolism compromises the optimal availability of indole and indole metabolites and can induce the onset of metabolic disorders, inflammation, liver steatosis, and decrease gut barrier integrity. Gut dysbiosis is regarded as one of the prime reasons for this deregulated microbial-derived indole metabolites. A number of indole metabolites from the gut bacteria have been identified recently displaying variable affinity towards xenobiotic nuclear receptors. Microbial metabolite mimicry concept can be used to design and develop novel indole-moiety-containing compounds with higher affinity towards the receptors and efficacy in preclinical studies. Such compounds may serve as therapeutic drugs in clinical trials in the future. In this article, I review L-trp metabolism in the host and gut microbiota and the various physiological functions, patho-physiologies associated with the microbial-released indole metabolites in the host, including the metabolite mimicry-based concept to develop tailored indole-containing novel experimental drugs.
OBJECTIVES: I. Evaluate the antitumor activity of interleukin-12 (IL-12) in patients with plateau phase multiple myeloma. II. Evaluate the toxic effects of IL-12 in these patients. III. Evaluate the effectiveness of IL-12 in augmenting T helper subsets in these patients.

OUTLINE: This is a randomized study. Patients are stratified by prior bone marrow transplantation (yes vs no) and by prior pneumococcal vaccine (Pnu-Immune-23) (yes vs no or unknown). Patients are randomized to one of two treatment arms: Arm I: Patients receive Haemophilus influenzae b vaccine (Hib TITER) and Pnu-Immune-23 on day 1 during week 1. Patients who have received Pnu-Immune-23 within the past 3 years receive Hib TITER but no Pnu-Immune-23. Patients receive low dose interleukin-12 (IL-12) subcutaneously (SQ) twice a week during weeks 1 and 2. Beginning on day 1 of week 3, patients receive high dose IL-12 SQ twice a week for an additional 12 weeks. Arm II: Patients receive Hib TITER and Pnu-Immune-23 as in arm I. Patients undergo observation during weeks 1-4, then receive low dose IL-12 SQ twice a week during weeks 5 and 6. Beginning on day 1 of week 7, patients receive high dose IL-12 SQ twice a week for an additional 12 weeks. Both arms: Patients without disease progression may continue to receive high dose IL-12 for an additional 14 weeks. Patients are followed every 3 months for the first 2 years, every 6 months for the next 3 years, and then annually thereafter until death.

PROJECTED ACCRUAL: A total of 40 patients (20 per arm) will be accrued for this study.
BACKGROUND: Polycystic ovary syndrome (PCOS) is a multifactorial disorder characterized by a broad spectrum of reproductive and metabolic perturbations, necessitating early timely diagnosis and management. PCOS is a multigenic disorder and ample evidence from family based, candidate gene and genome-wide association studies (GWAS) has implicated genetic factors in development and progression of PCOS. The first GWASs in Han Chinese population revealed prominent gene loci to be strong contenders in the etiopathogenesis of PCOS. However, different ethnic and geographical settings impact the genetic association pattern of PCOS.
METHODS AND RESULTS: In the current case-control replication study, we have genotyped previously identified polymorphisms viz. rs2479106 and rs10818854 of DENND1A and rs13405728 of LHCGR, rs4385527 and rs3802457 of c9orf3, rs705702 of RAB5B and rs1894116 of YAP1 in control (N = 247) and PCOS (N = 504) women by Sanger sequencing, and their association with PCOS susceptibility and its related traits was investigated. We found significant association of rs4385527 of c9orf3 and rs1894116 of YAP1 with decreased and increased PCOS susceptibility respectively in non-hyperandrogenic women. Trend towards association was also noted for rs2479106 of DENND1A and rs705702 of RAB5B. Additionally, polymorphisms also showed association with metabolic and androgen related traits in both controls and hyper- and non-hyperandrogenic women with PCOS.
CONCLUSIONS: Thus, this study shows that some, but not all polymorphisms previously identified in Han Chinese women, could contribute to the genetic pathophysiology of PCOS in Indian women, accentuating essentiality of conducting replication studies to elucidate the genetic predisposition profile of PCOS.
BACKGROUND: Currently licensed and approved malaria subunit vaccines provide modest, short-lived protection against malaria. Immunization with live-attenuated Plasmodium falciparum malaria parasites is an alternative vaccination strategy that has potential to improve protection.
METHODS: We conducted a double-blind, controlled clinical trial to evaluate the safety, side-effect profile, and efficacy of immunization, by means of mosquito bites, with a second-generation genetically attenuated parasite (GA2) - a mei2 single knockout P. falciparum NF54 parasite (sporozoite form) with extended development into the liver stage. After an open-label dose-escalation safety phase in which participants were exposed to the bites of 15 or 50 infected mosquitoes (stage A), healthy adults who had not had malaria were randomly assigned to be exposed to 50 mosquito bites per immunization of GA2, an early-arresting parasite (GA1), or placebo (bites from uninfected mosquitoes) (stage B). After the completion of three immunization sessions with 50 mosquito bites per session, we compared the protective efficacy of GA2 against homologous P. falciparum controlled human malaria infection with that of GA1 and placebo. The primary end points were the number and severity of adverse events (in stages A and B) and blood-stage parasitemia greater than 100 P. falciparum parasites per milliliter after bites from GA2-infected mosquitoes (in stage A) and after controlled human malaria infection (in stage B).
RESULTS: Adverse events were similar across the trial groups. Protective efficacy against subsequent controlled human malaria infection was observed in 8 of 9 participants (89%) in the GA2 group, in 1 of 8 participants (13%) in the GA1 group, and in 0 of 3 participants in the placebo group. A significantly higher frequency of P. falciparum-specific polyfunctional CD4+ and Vδ2+ γδ T cells were observed among participants who received GA2 than among those who received GA1, whereas GA2 and GA1 induced similar antibody titers targeting the P. falciparum circumsporozoite protein.
CONCLUSIONS: In this small trial, GA2 was associated with a favorable immune induction profile and protective efficacy, findings that warrant further evaluation. (Funded by the Bontius Foundation; ClinicalTrials.gov number, NCT04577066.).
