Flowers Are Evoked to Bring Us delicious Coffee

Agricultural Sciences 2024年第7期15卷 754-779页

作者： paula Cristina da silva Angelo Empresa Brasileira de Pesquisa Agropecuria (Embrapa Coffee/IDR-Paran) Londrina Brazil

Coffee is highly appreciated as stimulant. Brazil is the first producer and second consumer in the world. Flower evocation triggered by environmental signals is essential for adaptability and productivity, and despite that it is neglected and barely considered as a part of the reproductive cycle. Aiming to review molecular mechanisms producing phenological responses observed in the fields, orthologs to A. thaliana CO, FLC/FLM, FLT, SOC and VRN genes were identified in silico for C. arabica and its ancestors C. canephora and C. eugenioides. Protein structures and conserved domains, regulatory elements in promoters, and the related literature in both genera were accessed and compared. Hypotheses regarding Coffea spp. orthologs responsiveness to light and temperature signals at the tropics are proposed. Preliminary analysis of phenological data taken from early, intermediary and late C. arabica plants are included to illustrate the diversity regarding flower bud emission, which quite certainly is defined during flower evocation.

Five Year Follow up after Surgical Treatment of Type 2 Diabetes with Laparoscopic Sleeve Gastrectomy Associated with a Duodenal Ileal Interposition

Surgical Science 2024年第6期15卷 396-408页

Introduction: Type 2 diabetes mellitus (T2D) is a chronic disease, primarily caused by a combination of defective insulin secretion and the inability of insulin-sensitive tissues to respond to insulin. Laparoscopic sleeve gastrectomy associated with duodenal ileal interposition (SGDII) has been shown to be a feasible treatment option for patients with T2D, as it provides improvement and control of glycemia, dyslipidemia and arterial hypertension. The aim of this study was to evaluate the mid and long-term results of SGDII for the treatment of diabetic patients, considering diabetic remission, weight loss and postoperative complications. Materials and Methods: Retrospective study with 96 patients with T2D submitted to SGDII, between 2010 and 2016. The glycated hemoglobin (HbA1c) value Results: Sixty-one patients (62.8%) were male, and 36 patients (37.2%) were female. The average age was 50.9 years. Median BMI was 33.43 kg/m2. The incidence of major postoperative complications in the first 30 days was 2.1%, with no mortality. Dyslipidemia control was sustained, after five years, in 62% of the patients. The five years follow-up demonstrated that 80% of patients had T2D remission at one year, 74.5% at three years and 61.8% at five years. Univariate analysis demonstrated that preoperative values of HbA1c and BMI, preoperative use of insulin, gender, and 30-day complication were not predictors of remission at all study intervals. The average duration of the disease was nine years and the mean glycated hemoglobin before surgery was 8.95%. Conclusion: SGDII resulted in good glycemic control at 5-years follow-up and represents a valid alternative for the treatment of T2D.

Screening of Environmental Bacterial Strains for Wild Aedes Mosquito Larval Biocontrol

Open Journal of Applied Sciences 2024年第9期14卷 2431-2442页

The effectiveness of current control measures against Aedes mosquitoes remains low, resulting in persistent epidemics in urban areas. The emergence of resistant mosquito populations to chemical insecticides highlights the need for novel, environmentally friendly, cost-effective control strategies. This study explored the potential of environmental bacterial isolates to biocontrol wild Aedes larvae. Initially, we collected bacterial samples from infectious masses of Aedes fluviatilis larvae. The isolated bacteria were identified using biochemical, enzymatic, and molecular methods, including 16S rRNA sequencing and MALDI-TOF. Previously, Aeromonas hydrophila and Bacillus thuringiensis isolated from these infectious masses showed limited Aedes larval inhibition. Consequently, we screened additional environmental isolates from the bacteriotheque. Six isolates previously identified were tested: Chromobacterium violaceum, Enterobacter cloacae, Bacillus cereus, Bacillus sphaericus, and two strains of Bacillus thuringiensis israelensis. Among these strains, B. thuringiensis and C. violaceum exhibited significant inhibitory activities against wild Aedes larvae. Bacillus thuringiensis cultures grown under daylight conditions showed a slight ability to inhibit Aedes larvae. The potential of B. thuringiensis and C. violaceum strains studied, along with optimized culture growth conditions, will be further investigated to develop bioinsecticide products to provide safer and more sustainable alternatives for controlling larvae of Aedes mosquitoes.

Gravity Fault Subsidence and Beach Ridges Progradation in Quinta-Cassino (RS) Coastal Plain, Brazil

Ground penetrating radar (GPR) surveys have being applied to investigate very near-surface stratification of sedimentary units in coastal plains and to define their depositional conditions. This paper presents, however, low-frequency GPR survey to investigate fault-related depositional systems at greater depths. The Quinta-Cassino area in the Rio Grande do Sul Coastal Plain (RGSCP, Brazil) shows a wide strandplain that is made off by very long, continuous, and linear geomorphic features (beach ridges). This strandplain extends for ~70 km southward. The beach ridges show low-angle truncations against the Quinta escarpment, and also truncations in the strandplain. The traditional approach points that RGSCP was developed by juxtaposition of four lagoons/barrier systems as consequence of sea level changes;previous model assumes that no deformational episode occurred in RGSCP. The geophysical and geological surveys carried out in this area showed the existence of listric fault controlling the beach ridges in the escarpments and hanging-wall blocks. The radargrams could distinguish Pleistocene basement unit anticlockwise rotation, thickening of beach ridges radarfacies close to listric normal faults, and horst structures. These deformational features indicate that the extensional zone of a large-scale gravity-driven structure controlled the mechanical subsidence, the Holocene sedimentation and its stratigraphic and geomorphic features in the Quinta-Cassino area to build up an asymmetric delta. The results point to a new approach in dealing with RGSCP Holocene evolution.
