Psidium guajava (guava) is an important crop and economic resource in many tropical countries and Brazil stands out as one of its major commercial producers. The guava crop has been severely attacked by the plant parasitic nematode Meloidogyne enterolobii which has caused drastic reduction of productivity and, in some cases, even total loss of cultivated areas. The use of resistant rootstocks that are tolerant to these soil pathogens can be a low-cost solution to this pathogen, which has established itself as one of the major constraints for the cultivation of guava in Northeast Brazil. The objective of this work was to evaluate the reaction of P. guajava and P. guineense to M. enterolobii infection under greenhouse conditions, with an infection period of 60 days. 12 P. guineense, and 4 P. guajava were evaluated. The host response to the nematode infection was evaluated according to the following parameters: gill index (GI), reproductive factor (RF), and reduction of reproductive factor (RRF). Considering the RRF criteria, the P. guineense genotypes, AR1, AR3, AR4 and AR10 were considered resistant. The RF index was considered inadequate to evaluate resistance in the 60 days period, due the slow development of the parasite in P.guineense.

Ubiquitination is a kind of posttranslational modification of proteins in eukaryotes, and it plays an important role in the growth and development of organisms. The ubiquitination of proteins is a cascade enzymatic reaction involving three enzymes. The homologous to E6-AP carboxy terminus ubiquitin-protein ligases (HECT E3s) family is an important ubiquitin-protein ligases family. The family all have a HECT domain of approximately 350 amino acids in the C-terminus. However, studies on plant HECT E3s, such as structural features, prediction of HECT domain function, and their regulatory mechanisms, are very limited. In this paper, Arabidopsis thaliana HECT family genes were analyzed, including gene structure and functional domains and its limited known functions in protein degradation, gene transcription regulation, epigenetically regulation or other functions, finally speculate their roles in plant morphologies, aging or responsive to environmental stress.

Phytosanitary inspectors play an important role in diagnosing diseases in foreign plant material. However, some deficiencies have been detected in the detectionc ausing the entrance of many microorganisms. Therefore, it was of great interest to detect the presence of Clavibacter michiganensis subsp. michiganensis (Cmm) in foreign tomato and chili seed in the agricultural area of Sinaloa, Mexico, besides the growth and cell density of Cmm was evaluated in different selective media under continuous illumination and photoperiod. The results indicate that seeed of 35 varieties of tomatoes was collected; while for Chili seed were 18. This study was supported by farmers (225) which represent 79% of all growers and 32 business engaged in the sale of agro-supplies, provided seeds of varieties and hybrids. Those growers are from six areas (Culiacan, El Tamarindo, Navolato, Culiacan, El dorado and Badiraguato). For detection of Cmm in tomato seed, from 35, only four was variability considering Immunochromatography and ELISA techniques; however, considering chemical and physiological test, the result was negative. Similar results were in 18 varietes of chili seed, where eight showed variability to detect Cmm, and negative by chemical and physiological test. According to the growth and cell density of Cmm, the optimal medium was YDC under pH stable and continuous light conditions. It is recommended to consider the fusion of diagnostic techniques in the emission of a result.

The halophyte Distichlis palmeri (Vasey) is a plant resource with high potential to be harvested in the coastal areas of northwestern Mexico; enlarge the knowledge and domestication for its incursion into the agricultural sector, plays an important role for arid areas with saline intrusion problems. However, its productivity depends on the supplementary supply of nitrogen, as well as other essential macro and micronutrients. The microorganisms considered beneficial are an alternative to chemical fertilization, highlighting those Plant Growth Promoting Bacteria (PGPB). In the present study, the inoculation of the Bacillus amyloliquefaciens (B.a.) as a halobacterium PGPB was evaluated to know the response in seeds of Distichlis spicatai obtained from natural population from colorado river in Delta north of the Gulf of California. Wild seed was collected and germinated previously inoculated with B. a., and sowed in germinated beds. Later, seedlings were planted under field and salinity conditions in the coast of Hermosillo, Sonora. Three treatments were examined (T1: B.a., T2: Chemical fertilization, T3: Negative control), with four repetitions each treatment. Each repetition consisted of experimental plots of 5 x 5 m, with a separation of 1 m between them. The harvest was carried out 600 days after sowing. The results indicate that treatments inoculated with halobacteria B.a., showed significant results in crude protein, non-protein nitrogen, neutral detergent fiber and acid detergent fiber, as well as spike length and number of seeds. The results obtained suggests the feasibility of biofertilizers where biomass and seed production are significant compared to non-inoculated controls.

Many agriculturally important properties such as heterosis, inbreeding depression, phenotypic plasticity, and resistance for biotic and abiotic stresses are thought to be affected with epigenetic components. New discoveries related with epigenetics are likely to have a major impact on strategies for crop improvement in rice breeding. However, assessing the contribution of epigenetics to heritable variation in plant species still poses major challenges. Methylation of cytosine in DNA is one of the most important epigenetic mechanisms in plants. DNA methylation not only plays significant roles in the regulation of gene activity, but also it is related with genomic integrity. Although most of next generation sequencing (NGS) technologies do not require the use of target specific primer pairs to identify and study DNA cytosine methylation, validation studies of NGS uses selective primer pairs. Bisulfite sequencing technique is a gold method for DNA cytosine methylation studies. However, bisulfite sequencing requires the development of bisulfite primer pairs to selectively study DNA sequences of interest. In this study 9 bisulfite specific primer pairs were identified and validated. These primer pairs successfully amplified bisulfite converted and unconverted genomic DNA extracted from radicle and plumule of rice (Oryza sativa L.) seedlings. Results of the present study clearly revealed the occurrence of CG, CHG and CHH (H stands for C. T or A nucleotides) contents in studied DNA sequence targets were different indicating potential role of DNA cytosine methylation in these genes. Primer pairs reported in this study could be used to detect DNA methylation which is one of the most important epigenetic mechanisms affecting the development, differentiation or the response to biotic and abiotic stress in rice (Oryza sativa L.).

Acute osteomyelitis (AOM) is defined as an inflammation of the bone secondary to infection. Among the most common complications of AOM is the development of a periosteal abscess and the extension of the focus locally to muscle (pyomyositis) and/or joint (osteoarthritis). However, complications with much lower incidence have been described, including deep vein thrombosis (DVT) and septic pulmonary embolisms (SPE), mainly associated with S. aureus infections. The AOM + DVT + ESP triad is a fairly uncommon entity in the pediatric population; however, if it is not diagnosed and treated in time, it implies a high morbidity and mortality. Treatment, which must be early and aggressive, includes targeted antibiotic therapy, anticoagulation, and focused control surgery. In this article, we describe the case of a 14-year-old boy with disseminated staphylococcal infection associated with the triad AOM+ DVT + SPE.

Amyloidosis-associated kidney disease commonly manifests with chronic glomerular symptoms including heavy proteinuria predominantly albuminuria. Clinical presentation ranges from full-blown nephrotic syndrome, hematuria, and hypertension to renal failure. In India patients with chronic kidney disease are mainly attributed to hypertension and diabetes but an underlying etiology such as amyloidosis needs to be unearthed and shouldn’t be ignored as an etiology. We report a case of a 60-year-old man with hypertension and hypothyroidism who presented with frothy urine for several years, b/l pedal edema for 15 days. Over the past 3 months, there was a serial increase in creatinine. As per CKD-EPI equation, the patient was CKD-4. As the patient was suspected to be rapidly progressive renal failure; a renal biopsy was planned. Biopsy reports were suggestive of Amyloidosis. Glomerular, vascular, and tubulointerstitial deposition of amyloid was seen. Based on renal biopsy and IHC staining; the patient’s diagnosis was AA-associated secondary renal amyloidosis. Thus in this case renal amyloidosis was an unearthed etiology.

Bruxism, characterized by involuntary, repetitive jaw-muscle activity including clenching and grinding of teeth, can lead to significant dental and muscular complications. Conventional treatments—such as occlusal splints and behavioral therapy-may not fully address muscular hyperactivity. Botulinum toxin type A (BoNT-A), a neurotoxin that inhibits acetylcholine release at neuromuscular junctions, has emerged as a promising therapeutic option. This article reviews clinical studies regarding the efficacy of BoNT-A injections into masticatory muscles for bruxism management, with a focus on clinical outcomes, safety, and practical considerations.

The escalating volume of solid waste due to rapid urbanization, population growth, and industrialization poses significant environmental and public health challenges. Improper disposal of solid waste, especially organic and municipal garbage, leads to pollution of soil, air, and water, causing a surge in health risks and ecosystem degradation. Traditional waste management practices are often inefficient, expensive, and time-consuming. Composting and vermicomposting have emerged as eco-friendly, cost-effective, and sustainable alternatives for organic waste management. Vermicomposting, which employs earthworms to decompose organic waste into nutrient-rich compost, has shown potential in improving soil fertility, reducing pathogenic microbes, and recycling essential nutrients like nitrogen, phosphorus, and potassium. Various organic wastes such as agricultural residues, municipal waste, animal dung, and market garbage have been effectively treated through vermicomposting using species like Eisenia fetida and Eudrilus eugeniae. This review emphasizes the technological, environmental, and agricultural benefits of vermicomposting in transforming biodegradable solid waste into valuable compost, promoting sustainable waste management practices, and enhancing agricultural productivity.

Introduction: The annual rhythm of menarche was proposed to be due to climatic annual variations. The discovery that peaks of incidence of menarche were found in the same months in the North and the South Hemispheres made us to think this hypothesis was not correct. Then we proposed that periods of study (stress) and vacation (relaxation, fiesta) were better factors for this rhythm. If this is so, days of fiesta should present more menarches than current days. In the second hypothesis the age at menarche should be modified by the vacation-study rhythm. Thus, I tested two hypotheses: I) This rhythm and the age at menarche are conditioned by climate factors mostly seasonal variations. II) the contrast between expectancy of fiesta (relaxation) and stress is the main factor of the rhythm and the variation on the age at menarche during the year.Method: The monthly incidence and age at menarche were obtained from samples of girls in Santiago (Chile), Medellín (Colombia), Debrecen (Hungary), Chennai (India) with data collected directly in these countries. A sample from Barrinhas (Riberao Preto, Brazil) was taken from literature. The climatic hypothesis was tested knowing the main climatic parameters by the latitude of these cities. The annual study-vacation rhythm was obtained from the academic calendar at any city and from direct information of our colleagues working in these cities. A correlate between the climatic rhythm and the study-vacation rhythm with the incidence or age at menarche complete the refutation or affirmation of the hypotheses. Also, the expected peaks of menarche at significance fiesta-days or the birthday were studied directly form the calendar of holidays or the cultural information given by our colleagues. Results: In the five samples taken individually or together there were clear contradictions with the climatic hypothesis. On the contrary the fiesta-stress hypothesis shows a clear correlation with the monthly incidence and the age at menarche. Days of national, religious fiesta or the birthday showed greatly significant peaks of menarche. Conclusion: Data refute the climatic hypothesis of the annual rhythm of menarche and agree with the fiesta (vacation)-stress (study) hypothesis.
