Shade and Drought Shape Stomatal Kinetics in Beech Saplings.

Stomata and photosynthesis respond at different rates to rapid changes in light availability, resulting in different dynamics of water and carbon fluxes. Here, we investigated how growth conditions, drought, and potassium availability affect the dynamics of stomatal conductance and photosynthesis in response to rapid changes of irradiance in beech saplings (Fagus sylvatica L.). Two greenhouse experiments were conducted, one comparing saplings grown under sunlit conditions to those grown in shaded conditions, and the other testing the effects of edaphic drought and potassium supplementation on

Failure to Observe Stomatal ABA Responses in a Fern and a Lycophyte.

Stomatal closure induced by abscisic acid (ABA) is an important mechanism by which plants reduce transpiration under drought stress and is well studied in seed plants. However, ABA-induced stomatal closure in ferns and lycophytes has been reported in some studies but not in others, even within the same species, such as the fern Nephrolepis exaltata and the lycophyte Selaginella uncinata. Here, ABA-induced stomatal behaviour and ABA signalling components, including guard cell potassium ion (K+) and calcium ion (Ca2+) fluxes and vacuoles, were analysed in the seed plant Vicia faba, the fern N. e

Hydrogen sulfide modulates flagellin-induced stomatal immunity.

Stomata are natural pores through which plants exchange gases with the environment, mainly carbon dioxide and oxygen required for photosynthesis and respiration, as well as water vapor through evapotranspiration. However, they also serve as entry points for microbial pathogens such as Pseudomonas syringae pv. tomato (Pst) bacteria. To prevent microbe invasion, guard cells detect pathogen-associated molecular patterns (PAMPs), including the bacterial peptide flagellin (flg22), triggering stomatal closure. This study identifies hydrogen sulfide (H2S) and its cytosolic source L-CYSTEINE DESULFHYD

Dietary Antioxidant Index and the Risk of Recurrent Aphthous Stomatitis.

BACKGROUND: Recurrent aphthous stomatitis (RAS) is a common condition that affects the oral mucosa. Antioxidants are crucial in neutralizing free radicals in the body and may have a preventive role against RAS. This study aims to examine the association between dietary antioxidant index (DAI) and RAS occurrence. METHODS: This cross-sectional study was conducted on 144 individuals with RAS and 135 individuals without RAS. The dietary intake of the participants was assessed using the food frequency questionnaire. The DAI was applied to measure the antioxidant capacity of the diet. Logistic regr…

Вирус везикулярного стоматита в качестве платформы для измерения активности протекционистов.

Ингибиторы протеинов являются одними из самых мощных антивирусных препаратов. Они успешно применяются против таких вирусов, как вирус иммунодефицита человека (ВИЧ), вирус гепатита С (ГХВ) и острый острый респираторный синдром коронавирус 2 (SARS-COV-2). Поэтому для выявления ингибиторов, способных стать антивирусными препаратами, важное значение имеют средства скрининга ингибиторов. В этой статье мы описываем недавно разработанные клеточные и вирусные платформы для проверки ингибиторов. Мы разработали методы, представленные здесь путем генетически модифицирующего вирус сосудистого стоматита, м

Bovine papular stomatitis virus as a vaccine vector for cattle.

Virus vectored vaccines are not available commercially for cattle even though compelling potential applications exist. Bovine papular stomatitis virus (BPSV), a highly prevalent parapoxvirus, causes self-limited oral lesions in cattle. Ability of virus to accommodate large amounts of foreign DNA, induce low level of antiviral immunity, and circulate and likely persist in cattle populations, make BPSV an attractive candidate viral vector. Here, recombinant BPSV were constructed expressing either Bovine herpesvirus 1 (BoHV-1) glycoprotein gD (BPSVgD), or gD and gB (BPSVgD/gB). Immunization of BP…

Efficacy of curcumin for recurrent aphthous stomatitis: a systematic review.

BACKGROUND: Recurrent aphthous stomatitis (RAS) is the most common ulcerative lesion of the oral mucosa. The management of RAS is quite challenging with no definitive cure. OBJECTIVE: The present systematic review aimed to summarize the available evidence regarding the efficacy of curcumin in the management of RAS. METHODS: PubMed, Scopus and Web of Science databases were searched in June 2020 for all relevant studies. Clinical trials that assessed the efficacy of curcumin for the management of RAS were included. The primary outcomes were pain and/or clinical improvement. RESULTS: Eight stu…

Stomatitis And Everolimus: A Review Of Current Literature On 8,201 Patients.

BACKGROUND: Oral toxicities, such as mucositis and stomatitis, are some of the most significant and unavoidable side effects associated with anticancer therapies. In past decades, research has focused on newer targeted agents with the aim of decreasing the rates of side effects on healthy cells. Unfortunately, even targeted anticancer therapies show significant rates of toxicity on healthy tissue. mTOR inhibitors display some adverse events, such as hyperglycemia, hyperlipidemia, hypophosphatemia, hematologic toxicities, and mucocutaneous eruption, but the most important are still stomatitis a…

Invasive Microsporum canis causing rhinitis and stomatitis in a cat.

Microsporum canis is a pathogenic fungus that typically causes dermatophytosis in cats. This report describes a cat with a Microsporum canis infection causing invasive fungal rhinitis that extended through the hard palate, resulting in adjacent stomatitis. Treatment with itraconazole and terbinafine resolved the infection.

A 58-year-old patient, with maxillary edentulism, treated with complete denture, presented to the Clinic of Prosthetic Dentistry of the Faculty of Dental Medicine, University of Medicine and Pharmacy of Craiova, Romania, for pain of oral mucosa and bad stability of denture. The diagnosis of erythematous denture stomatitis as consequence of salivary flow reduction was establish after patient's clinical examination, …

Therapeutic effect of proaftol in treatment of recurrent aphthous stomatitis.

UNLABELLED: Recurrent aphthous stomatitis (RAS) is a quite frequent, painful, ulcerative disease that affects the lining of the oral cavity and has an unknown etiology. The aim of this article is to examine the impact of the medication proaftol on epithelization speed and severity of pain in patients with RAS. In this randomized, double-blind, placebo-controlled study respondents were divided into two groups where one group was treated with proaftol spray and the other with a placebo. Aphthae considered for treatment had a diameter of 5-6 mm. The participants were given instruction on the use …

Effect of bedtime on recurrent aphthous stomatitis in college students.

OBJECTIVE: In this study, we conducted a questionnaire-based survey at Sichuan University to investigate the potential effects of bedtime on recurrent aphthous stomatitis (RAS). STUDY DESIGN: An anonymous self-designed questionnaire was adopted to investigate the association between bedtime and RAS in college students at Sichuan University. Statistical analyses were used to identify risk factors for RAS and to explore the relationship between bedtime and RAS. RESULTS: One thousand six students were investigated. High frequency of colds (odds ratio [OR] 2.17; 95% confidence interval [CI] 1.52…

Efficacy and safety of probiotics in the treatment of Candida-associated stomatitis.

This study aimed at evaluating the short-term efficacy and safety of probiotics as an aid in the treatment of Candida-associated stomatitis in a randomised controlled trial. A total of 65 patients were randomly assigned to receive oral local antifungal agents alone (gargle 2% sodium bicarbonate solution for 30 s, wait 10 min and then apply 2% nystatin paste) or these agents plus local probiotics (the mixture of Bifidobacterium longum, Lactobacillus bulgaricus and Streptococcus thermophilus) three times per day for 4 weeks. Parameters related to hyperaemia, visual analogue scale scores, culture…
