Diet composition drives tissue-specific intensity of murine enteric infections.

Diet composition plays a large role in regulating gut health and enteric infection. In particular, synthetic "Western-style" diets may predispose to disease, while whole-grain diets containing high levels of crude fiber are thought to promote gut health. Here, we show that, in contrast to this paradigm, mice fed with unrefined chow are significantly more susceptible to infection with Trichuris muris, a caecum-dwelling nematode, than mice fed with refined, semi-synthetic diets (SSDs). Moreover, mice fed with SSD supplemented with inulin, a fermentable fiber, developed chronic T. muris burdens,

Metaproteomics reveals persistent and phylum-redundant metabolic functional stability in adult human gut microbiomes of Crohn's remission patients despite temporal variations in microbial taxa, genomes, and proteomes.

BACKGROUND: The gut microbiome plays a fundamental role in the human host's overall health by contributing key biological functions such as expanded metabolism and pathogen defense/immune control. In a healthy individual, the gut microbiome co-exists within the human host in a symbiotic, non-inflammatory relationship that enables mutual benefits, such as microbial degradation of indigestible food products into small molecules that the host can utilize, and enhanced pathogen defense. In abnormal conditions, such as Crohn's disease, this favorable metabolic relationship breaks down and a variety

Red Yeast Rice Plus Berberine: Practical Strategy for Promoting Vascular and Metabolic Health.

Lovastatin, the progenitor of the statin family, is in fact a naturally occurring compound produced by the yeast Monascus purpureus. Red yeast rice (RYR), a traditional Chinese food made by fermenting rice with M purpureus, is an herbal medicine that has been used for 1200 y as a therapy for problems related to circulation and digestion. RYR contains a range of compounds known as monacolins, of which monacolin K-renamed lovastatin by pharmaceutical researchers-was found to be the most potent inhibitor of cholesterol synthesis. Standardized extracts of RYR, providing 10 mg of monacolins daily,

Reproductive and offspring developmental effects following maternal inhalation exposure to methanol in nonhuman primates.

INTRODUCTION: In an effort to improve air quality and decrease dependence on petroleum, the federal government, industry, and other groups have encouraged development of alternative fuels such as methanol to substitute for gasoline or diesel fuel. Methanol is also a candidate to provide the hydrogen for fuel cells, which are being developed for a variety of power sources (including motor vehicle engines). Before people are exposed to increased concentrations of methanol, the potential health effects of such exposures require study. Methanol, a simple alcohol containing one carbon atom, occurs

The Beneficial Effects of Raffinee in Permanent Occulted Stroke Mice.

Ischemic stroke is a major cause of disability and mortality globally. Although thrombolytic therapy is routinely adopted in cases of ischemic stroke, various alternative natural neuroprotectants are also used as effective adjuvant therapies to recover neurofunction following ischemic stroke. Raffinee, a natural fermented product with strong antioxidant and neuroprotective activities, has antiatherogenic effects in animals and has exhibited neuroprotective effects in a clinical trial by recovering motor and sensory function following spinal cord lesion. This study reveals the advantageous effe

Apparent total tract nutrient digestibility of frozen raw, freeze-dried raw, mildly cooked, and retorted dog foods and their effects on fecal characteristics, metabolites, and microbiota of healthy adult dogs.

The objectives of this study were to determine how diets distinctly processed from the same raw batch to mimic common pet food formats may affect apparent total tract macronutrient digestibility (ATTD), gastrointestinal transit time (GTT), and fecal characteristics, metabolites, and the microbiota of healthy dogs. Ten spayed female adult beagles (age: 6.10 ± 1.20 yr; body weight: 8.63 ± 0.77 kg) were used in a replicated 5 × 5 Latin square design to test the following diet formats: retorted (RT), mildly cooked (sous vide [SV], steamed [ST]), and raw (high-pressure processed [HPP], freeze-dried

Molecular evolution of CO 2 -sensing ab1C neurons underlies divergent sensory responses in the Drosophila suzukii species group.

UNLABELLED: Organisms evolve behavioral and morphological traits to adapt to their ecological niches, yet the genetic basis of adaptation remains largely unknown. Drosophila suzukii has evolved a distinctive oviposition preference for ripe fruit, unlike most Drosophila species such as D. melanogaster , which prefer overripe fruit. Carbon dioxide (CO 2 ), a metabolic volatile that increases as fruit ripens and decays, may act as a critical ecological cue shaping these preferences. Here, we focus on D. suzukii and its sister species D. subpulchrella , which shows an intermediate preference, to i

A Review of the Role of Green Tea (Camellia sinensis) in Antiphotoaging, Stress Resistance, Neuroprotection, and Autophagy.

Tea is one of the most widely consumed beverages worldwide, and is available in various forms. Green tea is richer in antioxidants compared to other forms of tea. Tea is composed of polyphenols, caffeine, minerals, and trace amounts of vitamins, amino acids, and carbohydrates. The composition of the tea varies depending on the fermentation process employed to produce it. The phytochemicals present in green tea are known to stimulate the central nervous system and maintain overall health in humans. Skin aging is a complex process mediated by intrinsic factors such as senescence, along with extr

Prevalence of Salmonella typhi in among febrile patients in a tertiary care hospital of South West Rajasthan.

BACKGROUND: Salmonella enterica, serotype typhi, remains the predominant Salmonella species causing enteric fever in India. The mode of Salmonella typhi transmission is considered to be predominantly vehicle-borne through contaminated water or food. In India, the incidence of Salmonella typhi occurs between the months of April and June (dry season) followed by July and September (monsoon season). Typhoid fever may be difficult to distinguish clinically from other febrile illnesses and if left untreated, intestinal, neuropsychiatric, and other complications develop in some patients. OBJECTIVE:

Traditional botanical medicine is the primary mode of healthcare for most of the rural population in Arunachal Pradesh. MATERIALS AND METHODS: Field research was conducted between April 2006 and March 2009 with randomly selected 124 key informants using semi-structured questionnaire. The data obtained was analyzed through informant consensus factor

Avoidance of oxidative-stress perturbation in yeast bioprocesses by proteomic and genomic biostrategies?

AIMS: Bioprocess oxidative stress caused by many reactive oxygen species (ROS) can lead to largely irreversible perturbation of yeast bioprocesses. These include the production of proteins derived from recombinant DNA yeast technology (aerobically grown Saccharomyces cerevisiae). These proteins include rennin, amyloglucosidases (glucamylases), interferons, interleukins, insulin, monoclonal antibodies, tissue plasminogen activators (t-PA), sexually transmitted disease antigens, and measles, mumps and rubella antigens, growth hormones, somatotropin, blood clotting factors VIII and XIII. In addit

Occurrence, molecular characterization, and antimicrobial susceptibility of sorbitol non-fermenting Escherichia coli in lake water, fish and humans in central Oromia, Ethiopia.

Contaminated lake water and fish can be sources of bacterial pathogens of public health concern, including pathogenic E. coli. Within Ethiopia, specifically, Central Oromia, raw fish consumption is a common practice. Although there are few reports on occurrence of E. coli O157 in fish destined for human consumption and children under five years, information on the transmission pathways of E. coli O157 and other sorbitol non-fermenting (SN-F) E. coli from water-to-fish-to-human, and their virulence factors and antimicrobial resistant determinants along the fish supply chain is lacking. The stud

Final report of the safety assessment of Urea.

Although Urea is officially described as a buffering agent, humectant, and skin-conditioning agent-humectant for use in cosmetic products, there is a report stating that Urea also is used in cosmetics for its desquamating and antimicrobial action. In 2001, the Food and Drug Administration (FDA) reported that Urea was used in 239 formulations. Concentrations of use for Urea ranged from 0.01% to 10%. Urea is generally recognized as safe by FDA for the following uses: side-seam cements for food contact; an inhibitor or stabilizer in pesticide formulations and formulations applied to animals; inte

Health Risk and Protective Factors Among Hispanic Women Living in the U.S.-Mexico Border Region.

BACKGROUND/AIM: Aggressive tumor malignancies are a consequence of delayed diagnosis, epigenetic/phenotype changes and chemo-radiation resistance. Histone deacetylases (HDACs) are a major epigenetic regulator of transcriptional repression, which are highly overexpressed in advanced malignancy. While original chemotherapy drugs were modeled after phytochemicals elucidated by botanical screenings, HDAC inhibitors (HDACi) such as apicidin, trichostatin A (TSA) and butyrate were discovered as products of fungus and microbes, in particular, gut microbiota. Therefore, a persistent question remains a

A low fermentable oligo-di-mono saccharides and polyols (FODMAP) diet reduced pain and improved daily life in fibromyalgia patients.

BACKGROUND AND AIMS: Fibromyalgia (FM) is a chronic, rheumatic disease characterized by widespread myofascial pain, of unknown aetiology, having a major impact on quality of life (QOL). Available pharmacotherapy for FM is marginally effective. FM is associated with co-morbidities of gastrointestinal (GI) disorders and Irritable Bowel Syndrome (IBS). There is growing evidence that diets low in FODMAPs, "fermentable oligo-, di- or mono-saccharides and polyols" [Low FODMAP Diet (LFD)], are effective in treating IBS. The aim of this pilot study was to examine the effects of LFDs on symptoms of FM,

Long-term consumption of fermented pork fat-based diets differing in calorie, fat content, and fatty acid levels mediates oxidative stress, inflammation, redox imbalance, germ cell apoptosis, disruption of steroidogenesis, and testicular dysfunction in Wistar rats.

There is a dearth of experimental evidence available as to whether the consumption of fermented pork fat (FPF) food has any harmful effects on metabolism and reproduction due to its excessive calories, high fat content, and fatty acid methyl ester (FAME) levels. We hypothesized that exposure to a FPF-diet with excessive calories, a high fat content, and high FAME levels alters testicular physiology and metabolism, leading to permanent damage to the testicular system and its function. Thirteen-week-old male rats (n = 20) were assigned to a high-calorie, high-fat diet (FPF-H, fat-60%, 23 kJ/g),

Cefiderocol versus imipenem-cilastatin for the treatment of complicated urinary tract infections caused by Gram-negative uropathogens: a phase 2, randomised, double-blind, non-inferiority trial.

BACKGROUND: Carbapenem-resistant Gram-negative bacteria represent the highest priority for addressing global antibiotic resistance. Cefiderocol (S-649266), a new siderophore cephalosporin, has broad activity against Enterobacteriaceae and non-fermenting bacteria, such as Pseudomonas aeruginosa and Acinetobacter baumannii, including carbapenem-resistant strains. We assessed the efficacy and safety of cefiderocol versus imipenem-cilastatin for the treatment of complicated urinary tract infection in patients at risk of multidrug-resistant Gram-negative infections. METHODS: We did a phase 2, mult

Atypical Internal Yellowing of Papaya Fruit in Hawaii Caused by Enterobacter sakazakii.

Internal yellowing (IY) caused by Enterobacter cloacae and characterized by yellow discolored tissue surrounding the papaya (Carica papaya L.) seed cavity, diffuse margins, and the presence of a distinctly rotten odor was first reported in 1987 (3). Here we report the formation of atypical internal yellowing (AIY) in ripe papaya caused by the bacterium Enterobacter sakazakii. In surveys conducted from 2006 to 2007, 'Kapoho Solo' papayas grown in the Puna District of Hawaii Island were obtained from various packinghouses. After incubation at 27°C, the papayas were bisected and examined for symp

NTP technical report on toxicity studies of urethane in drinking water and urethane in 5% ethanol administered to F344/N rats and B6C3F1 mice.

Urethane, a byproduct of fermentation found in alcoholic beverages, is carcinogenic in rodents and is classified by the International Agency for Research on Cancer as a possible human carcinogen. The United States Food and Drug Administration nominated urethane for study because of the widespread exposure of humans through the consumption of fermented foods and beverages and because of a lack of adequate dose-response data about the carcinogenicity of urethane with and without the coadministration of ethanol. Comparative studies of urethane in drinking water and in 5% ethanol were conducted to…

Сосуществование Лактиплантацилла и Виккерхамомиц в верхнем слое сахарного тростника стимулирует потенциальное подавление патогенов и аэробную стабильность за счет увеличения производства лактической кислоты и уксусной кислоты.

Чтобы определить сосуществующие бактерии и дрожжи в верхнем слое сахарного тростника, которые определяют качество ферментации и повышают безопасность корма, мы манипулировали эпифитической микробиотой сверху сахарного тростника путем селективного подавления дрожжей (АФ) или бактерий с лактической кислотой (АБ) перед повторной цензурой, используя в качестве контроля неочищенные (КК) и стерилизованные стерилизованные силизы (НА). Результаты показывают, что высокоурожайное производство лактической кислоты и уксусной кислоты (p) < 0.05), лучшая аэробная стабильность и высокая плотность Лактипланта
