Abstract
PURPOSE A study analyzing the application of a protocol of comprehensive geriatric assessment (CGA) in older patients with lymphoma was carried out to allow frailty-based patient classification and individualized treatment. METHODS Lymphoma patients older than 70 years referred to the Geriatric Clinic at a tertiary hospital between May 2016 and March 2021 were included. The assessment protocol included comorbidity, polypharmacy, nutritional, functional, and mental status, geriatric syndromes, and life expectancy. CGA enabled patient classification into four groups (Type I to Type IV) based on frailty assessment instrument scoring and clinical, functional, and mental status. Variables were compared using parametric and non-parametric statistical tests and Kaplan-Meier survival curves. RESULTS Ninety-three patients (55.9% women) were included. Median age was 81.1 years (± 5.7). 23 patients (24.7%) were classified as robust (type I), 30 (32.3%) as pre-frail (type II) with potentially reversable deficits, 38 (40.9%) as frail (type III), and 2 (2.2%) as requiring palliative care (type IV). Patients received oncospecific treatment with modifications carried out in 64.5% of cases based on CGA results. Differences in overall survival (p = 0.002), response to treatment (p < 0.001) and likelihood of increased frailty (p = 0.024) were observed, with type III-IV patients showing significantly worse outcomes. CONCLUSION Performance of standardized, systematic CGA by geriatricians permits older lymphoma patients to be classified according to frailty, with significant differences in terms of clinical outcomes across groups. We propose incorporating CGA performed by geriatricians as part of the multidisciplinary care team to optimize therapeutic strategy for these patients.

Abstract
Sewage sludge generated in municipal wastewater treatment plants was used as a feedstock for biodiesel production via esterification/transesterification in a two-step process. In the first esterification step, greasy and secondary sludge were tested using acid and enzymatic catalysts. The results indicate that both catalysts performed the esterification of free fatty acids (FFA) simultaneously with the transesterification of triacylglycerols (TAG). Acid catalyst demonstrated better performance in FFA esterification compared to TAG transesterification, while enzymatic catalyst showed the ability to first hydrolyze TAG in FFA, which were esterified to methyl esters. In addition, FAME concentration using greasy sludge were higher (63.9% and 58.7%), compared with those of secondary sludge (11% and 16%), using acid and enzymatic catalysts, respectively. Therefore, only greasy sludge was used in the second step of alkaline transesterification. The alkaline transesterification of the previously esterified greasy sludge reached a maximum FAME concentration of 65.4% when using acid catalyst.

Abstract
The biobed systems were designed to retain and to degrade pesticides through the properties of a biomixture composed of straw (ST), topsoil and peat (PT) 2:1:1 v/v. The ST is the main substrate in the biomixture, as it allows the proliferation of fungi that promotes pesticide degradation. The use of readily available components in the biomixture is an important aspect to build a biobed. Therefore, potential use of readily available wastes as barley husk (BH), sawdust (SW) and oat husk (OH), as total or partial substitutes of ST were tested in pesticide degradation studies. Metabolite formation and the biological activities were also evaluated. Biomixture composed of OH was highly efficient in pesticide degradation, with t½ values of 28.6, 58.9 and 26.8 d for atrazine (ATZ), chlorpyrifos (CHL) and isoproturon (ISP). On the other hand, comparable for degrading capacities with the ST based biomixture were obtained with SW and BH, but only as partial replacement. Contrarily, high t½ values (more than 100 d) were obtained in biomixtures with total substitution of ST by SW or BH. Metabolite formation was observed in all biomixtures tested, but without clear formation patterns. Moreover, high and stable biological activity was observed in the biomixtures composed of OH. Therefore, our results demonstrated that ST can be partial or totally replaced by OH in the biomixture allowing an efficient degradation of pesticide mixture. However, it is recommended that ST can be only partially replaced by BH and SW in the biomixture to allow efficient pesticide degradation.

Abstract
BACKGROUND Smoking is a risk factor for gastroduodenal ulcer and gastric adenocarcinoma. However, the pathophysiological mechanisms induced by acute cigarette smoking in the human gastric mucosa are poorly understood. AIM To evaluate the effect of acute cigarette smoking, alone or with alcohol, on the gastric permeability to sucrose, a specific marker of mucosal damage in the stomach. SUBJECTS AND METHODS Twenty healthy volunteers (8 smokers/12 non-smokers) were studied. Each fasted subject ingested 500 ml of a 20% sucrose solution and the amount of sucrose excreted in a 5-hour urine collection was measured by gas chromatography Four sucrose permeability tests were carried out: 1. basal, 2. while smoking 5 cigarettes, 3. after drinking 50 ml of a 40 degrees alcoholic beverage, 4. a combination of 2+3. RESULTS Sucrose excretion increased after alcohol ingestion (40.5 +/- 6.0 mg vs 143.1 +/- 28.9 mg, p = 0.002), but was not modified by acute cigarette smoking (34.4 +/- 5.9 mg). When alcohol and cigarettes were simultaneously consumed, the increase in alcohol-induced sucrose excretion was significantly reduced (73.1 +/- 16.6 mg, p = 0.03). Basal sucrose excretion was similar in smokers and non-smokers. However, in acute cigarette smoking, a decrease in sucrose excretion was observed in smokers (p = 0.02) but not in non-smokers. CONCLUSIONS These results indicate that acute cigarette smoking may tighten the gastric mucosa in habitual smokers and this is associated with a smaller increase of gastric permeability induced by alcohol.

Abstract
A technique for the isolation of a posterior tooth with large distogingival caries and which needed endodontic therapy is described. To ensure a perfect seal, avoiding contamination or infiltration of the chemicals used for irrigation during the root canal therapy, a direct resin temporary restoration was done before placing the rubber dam as required for endodontic treatment.

Abstract
Since we have previously observed a genetic difference in the development of tolerance to the narcotic effect of ethanol in UChA and UChB rats when providing them with a 10% v/v ethanol solution as sole drinking fluid, experiments were performed in order to know whether the resistance to development of tolerance to ethanol in UChB rats was also exhibited after other regimens of ethanol administration, namely, a 2.76 g/kg ethanol IP injection 24 hr before the experiment, only 10% v/v ethanol solution as sole drinking fluid for 21 days, or receiving acutely a daily dose of 2.76 g/kg ethanol by gavage for seven days. Participation of serotoninergic neurons was tested by treating rats with p-chlorophenylalanine (p-CPA), a known serotonin depletor. Results show that UChA rats developed tolerance to ethanol-induced narcosis and hypothermia, while UChB rats developed it to narcosis only when they received acute oral doses of ethanol for 7 days and did not develop tolerance to hypothermia with any of the treatment regimens. p-CPA pretreatment did prevent the development of tolerance in both strains of rats, confirming the participation of serotoninergic neurons in ethanol tolerance in rats.
