Effects of gastric bypass bariatric surgery on gut microbiota in patients with morbid obesity.

The Western diet is associated with gastrointestinal dysbiosis, an active contributor to the pathophysiology of obesity and its comorbidities. Gastrointestinal dysbiosis is strongly linked to increased adiposity, low-grade inflammation, dyslipidaemia, and insulin resistance in individuals with morbid obesity. Bariatric bypass surgery remains the most effective treatment for achieving significant weight loss and alleviating obesity-related comorbidities.

Bacterial community shifts occur primarily through rhizosphere expansion in response to subsoil amendments.

To comprehensively evaluate the impact of agricultural management practices on soil productivity, it is imperative to conduct a thorough analysis of soil bacterial ecology. Deep-banding nutrient-rich amendments is a soil management practice that aims to improve plant growth and soil structure by addressing the plant-growth constraints posed by dense-clay subsoils. However, the response of bacterial communities to deep-banded amendments has not been thoroughly studied.

Exploring the antibiogram of soil isolates from an indian hospital precinct: link to antibiotic usage.

Objective: Hospitals serve as hotspots of antibiotic resistance. Despite several studies exploring antibiotic resistance in hospitals, none have explored the resistance profile of soil bacteria from a hospital precinct. This study examined and compared the antibiogram of the soil isolates from a hospital and its affiliated university precinct, to determine if antibiotic resistant bacteria were present closer to the hospital.

Attempts to limit sporulation in the probiotic strain BG01-4 through mutation accumulation and selection.

The use of bacterial spores in probiotics over viable loads of bacteria has many advantages, including the durability of spores, which allows spore-based probiotics to effectively traverse the various biochemical barriers present in the gastrointestinal tract. However, the majority of spore-based probiotics developed currently aim to treat adults, and there is a litany of differences between the adult and infant intestinal systems, including the immaturity and low microbial species diversity observed within the intestines of infants. These differences are only further exacerbated in premature infants with necrotizing enterocolitis (NEC) and indicates that what may be appropriate for an adult or even a healthy full-term infant may not be suited for an unhealthy premature infant.

Altered gastrointestinal tract structure and microbiome following cerebral malaria infection.

Cerebral malaria (CM) is the most severe form of malaria with the highest mortality rate and can result in life-long neurological deficits and ongoing comorbidities. Factors contributing to severity of infection and development of CM are not fully elucidated. Recent studies have indicated a key role of the gut microbiome in a range of health conditions that affect the brain, but limited microbiome research has been conducted in the context of malaria.

The Emerging Role of the Gut-Brain-Microbiota Axis in Neurodevelopmental Disorders.

Autism spectrum disorder (ASD; autism) is a prevalent neurodevelopmental disorder associated with changes in gut-brain axis communication. Gastrointestinal (GI) symptoms are experienced by a large proportion of individuals diagnosed with autism. Several mutations associated with autism modify cellular communication via neuronal synapses.

Comparing the Gut Microbiome in Autism and Preclinical Models: A Systematic Review.

Many individuals diagnosed with autism spectrum disorder (ASD) experience gastrointestinal (GI) dysfunction and show microbial dysbiosis. Variation in gut microbial populations is associated with increased risk for GI symptoms such as chronic constipation and diarrhoea, which decrease quality of life. Several preclinical models of autism also demonstrate microbial dysbiosis.

Towards Identifying Genetic Biomarkers for Gastrointestinal Dysfunction in Autism.

This study investigated genetic biomarkers for gastrointestinal dysfunction symptoms in order to provide further information on the genetic risk for GI dysfunction associated with autism. The single nucleotide polymorphisms of sixty participants with autism and/or gastrointestinal dysfunction were analyzed. The autism group had a moderate statistical significance for the Prolactin (PRL) (OR 6.

The Risks of Theft and Copyright Breach from Camera Use During Scientific Presentations: It's Time for a Debate.

Photographs are frequently taken during urological presentations and distributed on social media; they may represent a breach of copyright and, in instances of clinical photographs, a breach of data protection and human rights laws. Presenters and delegates attending conferences should be advised of the conference's copyright policies. Acceptable use of camera phones during scientific presentations should be debated by the scientific community.

Massive Photons: An Infrared Regularization Scheme for Lattice QCD+QED.

Standard methods for including electromagnetic interactions in lattice quantum chromodynamics calculations result in power-law finite-volume corrections to physical quantities. Removing these by extrapolation requires costly computations at multiple volumes. We introduce a photon mass to alternatively regulate the infrared, and rely on effective field theory to remove its unphysical effects.

Language disintegration in dementia: effects of etiology and severity.

The speech characteristics on a standardized picture description task of 26 subjects with presumed senile dementia of the Alzheimer type (SDAT) and 13 subjects with stroke-related dementia (SRD) were compared to 15 normal subjects over age 59 years. Compared to the normal subjects, the dementia subjects used fewer total words, fewer unique words, fewer prepositional phrases, fewer subordinate clauses, and more incomplete sentence fragments. Lexical deficits tended to be more severe than syntactic ones, confirming prior suggestions that lexicon is more vulnerable to disruption in dementia than syntax.

Intrusions and perseverations.

Twenty-two subjects with presumed senile dementia of the Alzheimer's type (SDAT), twenty-two with dementia other than SDAT, twenty with aphasia, and seventeen healthy controls over 50 years of age were examined for intrusions and perseverations. Perseverations were defined as the immediate inappropriate repetition of a prior response whereas intrusions were defined as the inappropriate repetition of prior responses after intervening stimuli. Intrusions and perseverations occurred in demented and aphasic subjects, but were rare in controls.

Altered patterns of word associations in dementia and aphasia.

The word associations of 38 demented, 17 aphasic, and 22 normal subjects were studied. Both normal and brain-injured subjects appear to make judgments about the grammatical class of the word stimulus. Certain stimulus words (especially nouns and adjectives) elicit paradigmatic responses whereas other words (especially verbs and adverbs) elicit syntagmatic responses.

A case of subcortical dementia due to sarcoidosis of the hypothalamus and fornices.

A patient with sarcoidosis involving predominantly the hypothalamus and fornices was evaluated for dementia. He showed a relative sparing of fund of knowledge and orientation. Memory skills, particularly short-term memory, were severely impaired.
