Discovery of the Underlying Mechanism of Ginger Juice Processed Ziziphi Spinosae Semen for Its Sedative-Hypnotic Effect on Insomnia Mice via Regulation of HPA Axis and cAMP/PKA Signaling Pathway.

Based on Traditional Chinese Medicine (TCM) theory, the efficacy and mechanism of Ginger juice processed Ziziphi Spinosae Semen (GJPZSS) for treating insomnia, particularly stress-related types, were investigated to provide empirical evidence. An insomnia model was induced in mice by DL-4-chlorophenylalanine (PCPA) and chronic tail clamping. The sedative effect was evaluated by behavioral tests. Serum components from GJPZSS were analyzed by UHPLC-Q-TOF-MS/MS, and 64 potential targets were identified. The cAMP signaling pathway was enriched as the core pathway by Kyoto Encyclopedia of genes and genomes (KEGG) analysis and was validated by molecular docking. GJPZSS was demonstrated to prolong sleep time, reduce immobility time, increase 5-hydroxytryptamine (5-HT) and gamma-aminobutyric acid (GABA) levels, decrease hypothalamic-pituitary-adrenal (HPA) axis levels, and suppress neuronal death. The reduction of the cyclic adenosine monophosphate (cAMP), protein kinase A (PKA), cAMP-response element binding protein (CREB) and brain-derived neurotrophic factor (BDNF) in the brain was also significantly inhibited. It was concluded that the sleep-improving effect of GJPZSS was mediated through the regulation of the HPA axis and the cAMP/PKA/CREB/BDNF signaling pathway.

Jamaica ginger paralysis. Forty-seven-year follow-up.

In 1930, thousands of Americans were poisoned by an illicit extract of Jamaica ginger ("jake") used to circumvent the Prohibition laws. A neurotoxic organophosphate compound, triorthocresyl phosphate (TOCP), had been used as an adulterant. The earliest reports were of peripheral neuritis, but later it was evident that an upper motor neuron syndrome had supervened. This TOCP poisoning apparently involved various cell groups and tracts in the spinal cord; the lesions was not peripheral at all. We interviewed 11 survivors of the illness residing in eastern Tennessee. Four were carefully examined. The principal findings showed the spasticity and abnormal reflexes of an upper motor neuron syndrome. One patient had mild disease, despite typical findings, and had lived a normal life.

The metabolism of zingerone, a pungent principle of ginger.

1. The metabolism of 4-(4-hydroxy-3-methoxyphenyl)butan-2-one (zingerone), a pungent principle of ginger, has been investigated in rats. 2. Oral or intraperitoneal dosage (100mg/kg) of zingerone resulted in the urinary excretion of most metabolites within 24 h, mainly as glucuronide and/or sulphate conjugates. While zingerone itself accounted for roughly 50-55% of the dose, reduction to the corresponding carbinol (11-13%) also occurred. Side chain oxidation took place at all three available sites and oxidation at the 3-position, giving rise to C6-C2 metabolites, predominated. About 95-97% of the dose was accounted for. 3. Appreciable (40% in 12 h) biliary excretion occurred. Biliary studies and studies in vitro using caecal micro-organisms indicated that several O-demethylated metabolites found in the urine are of bacterial origin.

Collaborative study of a modified method for the extraction of light filth from ground white pepper, cardamon, celery seed, coriander, and ginger.

An improved method has been developed for the extraction of light filth from 5 ground spices, ginger, white pepper, coriander, celery seed, and cardamom. The method, a modification of 44.120, utilizes a cold isopropanol defatting, followed by wet sieving and flotation of light filth from 40% isopropanol with HCl and mineral oil-heptane (85 + 15). Collaborative results show that the proposed method is more rapid to perform than the present official first action methods, 44.116 and 44.120, and yields better recoveries. The method has been adopted as official first action.

Effect of diet consistency, taste and calories on food intake of weanling rats with dorsomedial hypothalamic lesions.

Male weanling Sprague-Dawley rats with dorsomedial hypothalamic lesions (DMNL rats) primarily destroying the dorosomedial hypothalamic nuclei (DMN) showed significant hypophagia on lab chow chunks compared to sham-operated controls. When given a choice between lab chow in the form of chunks or powder, both controls and DMNL rats ate similar amounts of lab chow powder while DMNL rats ate less lab chow chunks. Total caloric consumption was the same as on chunks alone. When returned to lab chow chunks as the only source of calories, the pattern and magnitude of intake was again depressed for the DMNL rats. When offered a choice between Ginger Snaps cookies in chunk form versus powder, DMNL rats remained hypophagic in terms of chunk consumption while the intake from powder was similar in both controls and DMNL rats. When offered a choice between chunks of lab chow and Ginger Snaps, DMNL rats were again hypophagic on lab chow chunks, ate the same as the controls of the cookies, and the total caloric intake was of the same magnitude and pattern as observed in previous tests. The data suggest, but do not conclusively show, that DMNL rats are not hypophagic because they have an aversion to chewing hard food and that, when offered a diet similar in hardness to lab chow chunks i.e., hard cookies, will prefer the less tasty but nutritionally complete lab chow. They are apparently capable of choosing a diet for complete nutrition and, as previously reported, can meter calories competently.

Elongation of (omega-14C)oleic acid and (omega-14C)nervonic acid.

During feeding experiments with [omega-14C]oleic acid and [omega-14c]nervonic acid to adult rats, 14C-labelled C26, C28 and C30 fatty acids were recovered from the intestinal mucosa, liver, plasma, kidney and stools. The structures of these fatty acids were determined by g.l.c., radio-g.l.c. and mass spectrometry. The Schmidt and Ginger degradation methods indicated that most of the 14C found in these extra-long fatty acids remained in the omega position. These radioactive extra-long fatty acids were found mainly in the polar lipids of rats killed 3 or 15 h after being fed on labelled oleic acid or nervonic acid. Rats killed 63 h later yielded only traces of these extra-long fatty acids. When the rats were given antibiotics or received the same radioactive fatty acids by intravenous injection, the labelled extra-long fatty acids could not be detected in any of the tissues. We conclude that they were probably synthesized by elongation of oleic acid and nervonic acid by intestinal micro-organisms (probably yeasts) and then absorbed by the intestinal mucosa.

Involvement of molybdenum in feather growth.

A poor hatchability syndrome, characterised by a high incidence of weak chickens, with clubbed down and long ginger hairs, in commercial broiler breeding stock was investigated. 2. If the weak chick were given a single oral treatment of ammonium molybdate (40 microgram Mo/chick at 1 d), there was a reduction in subsequent mortality in both sexes and an increase in the growth rate of feathers in males, but not in females.

The analysis of essential oils and extracts (oleoresins) from seasonings--a critical review.

A critical review of the analytical methods employed for the determination of the relevant components of seasonings is presented. Where the available methods were inadequate, new ones have been devised. Particular emphasis has been placed on those methods of analysis that provide a rapid and sufficiently accurate appraisal of seasoning extracts and essential oils from seasonings under routine control laboratory conditions. At the same time, the margin of error of these methods has been determined. The individual seasoning extracts were assessed according to the following criteria: (1) essential oil--cardamom, laurel leaves, cloves, origanum (marjoram), sage, and thyme; (2) essential oil and nonvolatile lipids--dillseed, coriander, caraway, mace, nutmeg, pimento (allspice), and celery seed; (3) essential oil and/or pungent ingredients--capsicum, ginger, and pepper; (4) essential oil and/or coloring matter--turmeric (curcuma) and paprika; (5) essential oil and other components--garlic, onion, and cinnamon.

Survey to inform personalised prescribing in a British South Asian community: pharmacogenomics and traditional medicine use.

BACKGROUND: Pharmacogenomics (PGx) uses genetic information to personalize medication, reducing adverse reactions and improving efficacy. Despite its promise, low public awareness and disparities in PGx acceptability among under-represented groups may exacerbate health inequalities. The objective of this study was to elucidate a British South Asian community's attitudes toward personalised prescribing. METHODS: Adults of Bangladeshi or Pakistani ancestry from the Genes & Health (G&H) study completed a survey. Community feedback guided theme prioritization. Multivariable logistic regression analyses (controlling for age and gender) explored relationships among survey variables, and case-control Genome Wide Association Studies (GWAS) and candidate variant enrichment analysis examined the genetic architecture underlying herbal remedy use. RESULTS: Out of 553 respondents (57% female, mostly aged 25-54), 72% reported medication inefficacy, and 54% experienced side effects. Herbal remedies were widely used (66%), notably Black seed (39%), Turmeric (37%), and Ginger (36%). Participants who reported not using traditional or herbal medicines had higher medication adherence MARS-5 scores (Odds Ratio (OR) 1.10, 95% Confidence Interval (CI) 1.05-1.16, p&#x2009;<&#x2009;0.0002). All three commonly used herbal remedies inhibit the pharmacogenomically variable CYP2C9 enzyme responsible for metabolising commonly used medications. 58% of respondents were willing to provide DNA samples for PGx testing, yet 70% agreed that they would be more likely to take medication as instructed if PGx results suggested the medicine would suit them. Concerns about PGx testing were common (27%), especially among non-English speakers. Most (69%) were concerned about misuse of PGx data, particularly by pharmaceutical companies (82%). Importantly, 87% demanded stronger PGx data protections compared to other health data. CONCLUSIONS: Compared to a national UK population, the surveyed subpopulation reported higher rates of adverse drug reactions (ADRs) and perceived medication inefficacy, yet fewer respondents indicated willingness to undergo PGx testing. This highlights the need for tailored implementation strategies and underscores the importance of engaging underrepresented populations in policy development. The inverse relationship between medication adherence and herbal remedy use indicates an association between cultural health practices and medication behaviours that merits further investigation. Increased awareness of the common use of these CYP2C9 inhibitors and further research into the genetic architecture underlying herbal remedy use are warranted.

The Jake Walk Blues. A toxicologic tragedy mirrored in American popular music.

In 1930 thousands of cases of muscle pain, weakness of upper and lower extremities, and minimal sensory impairment occurred in the United States. The illness was caused by the consumption of an adulterated Jamaica ginger extract ("Jake"), an illicit beverage then popularly used in the southern and midwestern United States to circumvent prohibition statutes. The additive tri-ortho-cresyl phosphate caused severe, only partially reversible damage to the spinal cord and peripheral nervous tissue. Victims with resultant gait impairment, sometimes permanent, were said to have the "Jake Leg" or "Jake Walk." Twelve commercial phonographic recordings made between 1928 and 1934 by southern rural artists, white and black, refer to Jake or Jake-induced infirmity. These reveal preepidemic cultural familiarity with Jake, and the later, postepidemic performances reflect a whimsical, even cynical, cultural attitude that those with "Jake Leg" were suffering the wages of sin and should not be regarded as objects of pity or sympathy.

Whole genome sequence-based association analysis of African American individuals with bipolar disorder and schizophrenia.

In studies of individuals of primarily European genetic ancestry, common and low-frequency variants and rare coding variants have been found to be associated with the risk of bipolar disorder (BD) and schizophrenia (SZ). However, less is known for individuals of other genetic ancestries or the role of rare non-coding variants in BD and SZ risk. We performed whole genome sequencing of African American individuals: 1,598 with BD, 3,295 with SZ, and 2,651 unaffected controls (InPSYght study). We increased power by incorporating 14,812 jointly called psychiatrically unscreened ancestry-matched controls from the Trans-Omics for Precision Medicine (TOPMed) Program for a total of 17,463 controls. To identify variants and sets of variants associated with BD and/or SZ, we performed single-variant tests, gene-based tests for singleton protein truncating variants, and rare and low-frequency variant annotation-based tests with conservation and universal chromatin states and sliding windows. We found suggestive evidence of BD association with single-variants on chromosome 18 and of lower BD risk associated with rare and low-frequency variants on chromosome 11 in a region with multiple BD GWAS loci, using a sliding window approach. We also found that chromatin and conservation state tests can be used to detect differential calling of variants in controls sequenced at different centers and to assess the effectiveness of sequencing metric covariate adjustments. Our findings reinforce the need for continued whole genome sequencing in additional samples of African American individuals and more comprehensive functional annotation of non-coding variants.

A Multitrait Locus Regulates Sarbecovirus Pathogenesis.

Infectious diseases have shaped the human population genetic structure, and genetic variation influences the susceptibility to many viral diseases. However, a variety of challenges have made the implementation of traditional human Genome-wide Association Studies (GWAS) approaches to study these infectious outcomes challenging. In contrast, mouse models of infectious diseases provide an experimental control and precision, which facilitates analyses and mechanistic studies of the role of genetic variation on infection. Here we use a genetic mapping cross between two distinct Collaborative Cross mouse strains with respect to severe acute respiratory syndrome coronavirus (SARS-CoV) disease outcomes. We find several loci control differential disease outcome for a variety of traits in the context of SARS-CoV infection. Importantly, we identify a locus on mouse chromosome 9 that shows conserved synteny with a human GWAS locus for SARS-CoV-2 severe disease. We follow-up and confirm a role for this locus, and identify two candidate genes, CCR9 and CXCR6, that both play a key role in regulating the severity of SARS-CoV, SARS-CoV-2, and a distantly related bat sarbecovirus disease outcomes. As such we provide a template for using experimental mouse crosses to identify and characterize multitrait loci that regulate pathogenic infectious outcomes across species. IMPORTANCE Host genetic variation is an important determinant that predicts disease outcomes following infection. In the setting of highly pathogenic coronavirus infections genetic determinants underlying host susceptibility and mortality remain unclear. To elucidate the role of host genetic variation on sarbecovirus pathogenesis and disease outcomes, we utilized the Collaborative Cross (CC) mouse genetic reference population as a model to identify susceptibility alleles to SARS-CoV and SARS-CoV-2 infections. Our findings reveal that a multitrait loci found in chromosome 9 is an important regulator of sarbecovirus pathogenesis in mice. Within this locus, we identified and validated CCR9 and CXCR6 as important regulators of host disease outcomes. Specifically, both CCR9 and CXCR6 are protective against severe SARS-CoV, SARS-CoV-2, and SARS-related HKU3 virus disease in mice. This chromosome 9 multitrait locus may be important to help identify genes that regulate coronavirus disease outcomes in humans.
