Gut bacterial ClpB-like gene function is associated with decreased body weight and a characteristic microbiota profile

2020

[Background]: The chaperone ClpB, a bacterial protein, is a conformational antigen-mimetic of α-melanocyte-stimulating hormone (α-MSH) implicated in body weight regulation in mice. We here investigated the potential associations of gut bacterial ClpB-like gene function with obesity status and gut microbiota in humans.

Compensatory IgM to the Rescue: Patients with Selective IgA Deficiency Have Increased Natural IgM Antibodies to MAA-LDL and No Changes in Oral Microb…

2021

Abstract IgA is the most abundant Ab in the human body. However, most patients with selective IgA deficiency (SIgAD) are asymptomatic. IgM, and to lesser extent IgG Abs, are generally presumed to compensate for the lack of IgA in SIgAD by multiplying and adopting functions of IgA. We used data from the Northern Finland Birth Cohort 1966 to investigate whether SIgAD patients have differences in levels of natural Abs to oxidized epitopes compared with 20 randomly selected healthy controls. First, we screened the saliva and serum samples from the Northern Finland Birth Cohort 1966 cohort (n = 1610) for IgA concentration. We detected five IgA-deficient subjects, yielding a prevalence of 0.3%, w…

Linking Human Milk Oligosaccharides, Infant Fecal Community Types, and Later Risk To Require Antibiotics

2020

Human milk is the sole and recommended nutrition for the newborn infant and contains one of the largest constituents of diverse oligosaccharides, dubbed human milk oligosaccharides (HMOs). Preclinical and clinical association studies indicate that HMOs have multiple physiological functions largely mediated through the establishment of the gut microbiome. Until recently, HMOs were not available to investigate their role in randomized controlled intervention trials. To our knowledge, this is the first report on the effects of 2 HMOs on establishing microbiota in newborn infants. We provide a detailed description of the microbiota changes observed upon feeding a formula with 2 HMOs in comparis…

Effects of passiflora incarnata and midazolam for control of anxiety in patients undergoing dental extraction

2017

Background Anxiety symptoms are frequently observed in dental patients, whether they are undergoing simple or more invasive procedures such as surgery. This research aimed to compare the effects of Passiflora incarnata and midazolam for the control of anxiety in patients undergoing mandibular third molar extraction. Material and Methods Forty volunteers underwent bilateral extraction of their mandibular third molars in a randomized, controlled, double-blind, crossover clinical trial. Passiflora incarnata (260 mg) or midazolam (15 mg) were orally administered 30 minutes before surgery. The anxiety level of participants was evaluated by questionnaires and measurement of physical parameters, i…

Helicobacter pylori and some aspects of gut microbiota in children

2018

Helicobacter pylori infection in children differs from infection in adults in many aspects. The rate of infection, epidemiology, clinical presentations and complications, the applicability of diagnostic tests, antibiotic resistance, treatment options, and success rates differ significantly. Due to all these differences, management guidelines for children and adults differ also substantially. In 2017, the Updated ESPGHAN and NASPGHAN Guidelines on the management of H. pylori infection in children were published, emphasizing the differences in clinical presentation and indications for treatment, stating that the primary goal of clinical investigation in children is to identify the cause of up…

Starpdisciplinārie pētījumi medicīnas koledžās : tēžu krājums

2021

Latvijas Universitātes 79. starptautiskās zinātniskās konferences “Starpdisciplinārie pētījumi medicīnas koledžās” tēzes raksturo medicīnas koledžās veikto pētījumu daudzpusību, pētniecības kvalitāti un arī lietišķumu, kas šogad izceļas ar raksturvārdiem “drošība” un “atbildība”. Konferencē prezentēto un diskutēto jautājumu loks ievērojami pārsniedz veselības aprūpē apskatīto jautājumu loku un veicinās studentus, pētniekus un sociālos partnerus aktīvāk sadarboties ne tikai studiju kvalitātes uzlabošanā, bet arī pētniecībā.

Biodiversità nella dendroflora italiana

2013

Nella flora vascolare indigena d’Italia, costituita da circa 7000 taxa specifici e infraspecifici, quelli arborei sono rappresentati da un modesto numero di unità. Tra gimnosperme e angiosperme non si superano 200 specie. Diversificano e arricchiscono la dendroflora italiana specie legnose policormiche o arbustive che, con l’età e in particolari condizioni, possono assurgere a veri e propri alberi. Vi contribuiscono anche espressioni genetiche di classiche specie arboree variamente interpretate a livello tassonomico. La dendroflora qui esaminata si riferisce a 53 generi (7 gimonosperme e 46 angiosperme). I taxa specifici e infraspecifici sono 188 (21 gimnosperme e 167 angiosperme). Non poch…

Ancient or recent? Insights into the temporal evolution of the Bruniaceae

2008

AbstractThe Bruniaceae are a South African plant family endemic to the Cape Floristic Region with one geographic outlier (Raspalia trigyna) in the Natal Province. Recent molecular phylogenetic analyses have cast new light upon inter- and intra-generic relationships within the family. The present work uses those data to gain insights into the temporal evolution of Bruniaceae by inferring a molecular clock. For calibration, the inferred age of Berzelia cordifolia (3–5My) was used, based on its distribution restricted to the geologically young limestone area around Bredasdorp. The results are consistent with the purported Cretaceous age of the family (‘palaeoendemics’), but also suggest that m…
