Abstract
This study aimed to characterize the changes in serum inflammatory mediators in hospitalized patients with COVID-19 correlating with death. The study includes 58 participants: i) inpatients (n = 37): patients suffering from severe acute respiratory syndrome due to COVID-19, who were admitted at Intensive Care Unit (ICU) recovered and who died and ii) control group (n = 21): community volunteers. Inflammatory mediators evaluated interleukin-2 (IL-2), interleukin-4 (IL-4), interleukin-6 (IL-6), interleukin-10 (IL-10), interleukin-17 (IL-17), interferon-gamma (IFN-γ) and interferon-gamma protein levels (IFN-γ), as well as, Urea, LDH, D-dimer, TAP/INR, AST, ALT and lymphocytes. Our results suggest that high levels of inflammatory markers, such as pro-inflammatory cytokines, and laboratory parameters, such as low levels of lymphocytes and high levels of IL-6, are associated with disease severity, especially in individuals who died. Constant measurement and monitoring of these inflammatory parameters is an effective tool in clinical practice, and it can help choosing appropriate therapies during the course of the disease.

Abstract
This study aimed to profile the clinical progression, demographics, and oxidative status of COVID-19 patients, correlating with disease severity. The study included 143 participants: 93 patients with COVID-19 (28 outpatients, 65 inpatients), and 50 control participants. Thiobarbituric acid reactive substance (TBARS) was used as an oxidative damage marker. Antioxidant activity was assessed via quantification of Vitamin C, sulfhydryl groups, ferric reduction ability of plasma (FRAP), Uric acid (UA), and evaluation of delta-aminolevulinate dehydratase (δ-ALA-D) enzymatic activity. Geriatric patients, especially men, with comorbidities such as obesity and/or chronic diseases were more likely to develop the most severe form of COVID-19. The activity of the δ-ALA-D was lower in inpatients, and there was no significant difference with the outpatient. Antioxidants decreased in COVID-19 groups, while lipid peroxidation increased. FRAP and Vitamin C decreased with evolution of the disease. Oxidative stress could be used as a predictor of worsening clinical condition.

Abstract
The aim of the current study was to determine the activity of the delta-aminolevulinate dehydratase (δ-ALA-D) enzyme, oxidative stress biomarkers and the expression of cytokines in those infected with influenza B virus (IBV). To evaluate the activity of the δ-ALA-D enzyme, lipid peroxidation was estimated as levels of thiobarbituric acid reactive substances, protein and non-protein thiol groups, ferric-reducing antioxidant power (FRAP), vitamin C concentration and cytokine levels in IBV-infected individuals (n = 50) and a control group (n = 30). δ-ALA-D activity was significantly lower in IBV-infected individuals compared with controls, as well as levels of thiols, vitamin C and FRAP. Lipid peroxidation and cytokine levels of IL-6, IL-10, IL-17A and IFN-y were statistically higher in the IBV group. In conclusion, we found evidence of the generation of oxidants, the depletion of the antioxidant system, decrease in the activity of the δ-ALA-D enzyme and an increase in the synthesis of cytokines, thus contributing to a better understanding of oxidative and inflammatory pathways during IBV infection.

Abstract
This study aimed to investigate the effects of delivery type (normal or caesarean) on the antioxidant and oxidative capacity of colostrum collected shortly after delivery. A total of 61 parturients were included in the study and divided into two groups: those who underwent vaginal delivery (n = 36) and those who underwent elective caesarean section (n = 25). Colostrum samples were collected by manual milking up to 48 h post parturition and analysed for thiol groups (-SH), vitamin C, ferric reducing ability (FRAP), nitrate/nitrite oxides (NOx), and advanced oxidation protein products (AOPP). Colostrum levels of -SH (p = 0.0042), vitamin C (p = 0.0455), and FRAP (p = 0.0374) were significantly lower in the vaginal delivery group. The results suggest that vaginal delivery, compared to caesarean section, is associated with lower levels of antioxidants in colostrum and the mode of delivery plays an important role in the composition of antioxidants in maternal colostrum that help protect newborns from oxidative damage.IMPACT STATEMENTWhat is already known on this subject? Colostrum is the first biological fluid produced by the mother after delivery and is responsible for a child's growth, cognitive development and health. It is known that childbirth can cause oxidative imbalance, and its effects have already been evaluated in maternal and foetal blood, however, there are few studies evaluating the effects of childbirth on colostrum composition.What do the results of this study add? Previously, a study showed that caesarean section caused greater oxidation of colostrum compared to vaginal delivery. Thus, we sought to evaluate other markers (thiol groups, vitamin C, ferric reducing ability, nitrate/nitrite oxides, and advanced oxidation protein products), in a short period of time after delivery, in order to elucidate this still little discussed issue. Unlike the previous one, our study suggests that vaginal delivery, compared to caesarean section, is associated with lower levels of antioxidants in colostrum, which may make it difficult to protect newborns from oxidative damage.What are the implications of these findings for clinical practice and/or further research? Our study suggests that normal delivery can influence the antioxidant composition of maternal colostrum, and it is debateable for future clinical practice to improve eating habits during pregnancy and lactation, in order to strengthen the antioxidant capacity of colostrum and reduce oxidative damage to newborns.

Abstract
INTRODUCTION Oxidative stress is closely related to the pathophysiology of gestation, where the placenta is susceptible to oxidative damage, contributing to the onset of gestational complications. Currently, few studies evaluate the use of oxidative markers for prediction of risk of gestational complications. However, there are some reports that suggest these biomarkers as potential prognostic biomarkers. Therefore, the objective of this study was to compare the biomarkers of oxidative stress from gestations with and without complications, and also evaluate the delta of variation in these markers from the first gestational trimester. MATERIAL AND METHODS A total of 45 pregnant women were evaluated during the three gestational trimesters, of whom 15 developed gestational complications by the end of gestation. The evaluated oxidative damage markers were thiobarbituric acid reactive substances and nitric oxide dosage. Evaluation of the antioxidant system was performed by the quantification of vitamin C, sulfhydryl groups, total antioxidant capacity, plasmatic iron reduction ability, the evaluation of catalase and delta-aminolevulinate dehydratase enzymatic activity. RESULTS According to the results, the markers of oxidative damage are increased, and the antioxidant profile decreased, in the third trimester of complicated pregnancies as compared to uncomplicated pregnancies. Moreover, the delta of variation in both oxidative damage markers and antioxidants was higher in complicated gestations as compared to uncomplicated gestations, thus suggesting a higher oxidative stress in pregnancies with complications. CONCLUSIONS Oxidative stress parameters appear altered in pregnant women with gestational complications. The markers to oxidative stress can be possible biomarkers, helping in understanding mechanisms underlying the associations between complications during pregnancy and various health outcomes.

Abstract
Aims: The objective of this study was to investigate the effect of the type of delivery (vaginal and cesarean) on the activity of the enzyme delta-aminolevulinate dehydratase (δ-ALA-D), which as yet has not been studied, and the markers of oxidative stress.Methods: Seventy-six mothers and their newborns were divided into two groups: normal birth (VD) and elective cesarean section (ECS). Samples of maternal and umbilical cord blood were collected up to 5 min after birth. Thiobarbituric acid reactive substances (TBARS), advanced oxidation protein products (AOPP), protein thiol (P-SH), nonprotein (NP-SH), the ferric reducing ability of plasma (FRAP), total antioxidant capacity (TAC), catalase, and δ-ALA-D enzyme activity were tested.Results: TBARS and AOPP were significantly higher in mothers of the VD group, while P-SH, NP-SH, FRAP and TAC were reduced. In newborns, TBARS and AOPP did not differ between the groups; however, in the VD group, there was a decrease in P-SH, NP-SH, FRAP, TAC, and catalase. The activity of the δ-ALA-D enzyme was decreased in mothers and neonates born by VD.Conclusions: Mothers undergoing VD had higher levels of free radicals and lower antioxidant defenses, while their newborns decreased antioxidant defenses likely to contain the oxidative imbalance. The inhibition of the δ-ALA-D enzyme in this scenario allows its use as a useful marker of oxidative stress in different obstetric settings.

Abstract
The purpose is to determine markers of oxidative stress related to the longer and shorter duration of labor (DOL) of pregnant women in the umbilical cord blood of neonates, not yet studied. Blood samples from the umbilical cord were collected from pregnant women with normal delivery and classified according to DOL in two groups: a group with DOL less than 310 min (n = 33) and a group with DOL greater than or equal to 310 min (n = 35). The oxidative stress parameters were analyzed by the quantification of thiobarbituric acid reactive substances (TBARS), nitrate/nitrite (NOx), protein thiol groups (P-SH) and non-protein (NP-SH), vitamin C and plasma iron reduction capacity (FRAP), in addition to the activity of the enzyme delta-aminolevulinate dehydratase (δ-ALA-D). The activity of the δ-ALA-D enzyme was shown to be decreased in longer DOL, however, the oxidant parameters and antioxidants were higher in the longer DOL, with the exception of NP-SH that was lower. The longer maternal DOL time is related to the alteration of δ-ALA-D enzyme activity and other parameters in neonates, suggesting an increase in the passage of maternal oxidative markers by umbilical cord blood.

Abstract
Objective: This study aimed to evaluate the activity of
delta-aminolevulinate dehydratase (δ-ALA-D) and oxidative stress
biomarkers in pregnant women with gestational diabetes mellitus (GDM), in order
to demonstrate the involvement of oxidative stress in this condition, which
presents pathophysiology still undetermined. Methods: δ-ALA-D activity, lipid peroxidation estimated as the
levels of thiobarbituric acid reactive substances (TBARS), protein (P-SH) and
non-protein thiol (NP-SH) content, catalase (CAT) activity and concentration of
vitamin C (VIT C) in samples of pregnant women with GDM
(n = 48) and in healthy pregnant women
(n = 30), who constituted the control
group. Results: The δ-ALA-D activity was significantly lower in
pregnant women with GDM compared to controls, as well as levels of thiols, VIT C
and CAT activity. Lipid peroxidation was higher in GDM group. Discussion: The results suggest that the main factor for the

Abstract
BACKGROUND Patients with ST-segment elevation (STEMI) have totally occluded vessels, while patients with non-ST-segment elevation (NSTEMI) present partial vessel occlusion, which may generate different levels of Reactive Oxygen Species (ROS). Objectives: The aim of this study was to compare the oxidative profile in AMI patients with ST segment elevation and non-STEMI as well as control subjects. METHODS This study was carried with 46 AMI patients divided into STEMI and NSTEMI. The control group consisted of 40 healthy subjects. Oxidative stress profile was evaluated analyzing carbonyl protein (PCO), lipid peroxidation (TBARS), ischemia-modified albumin (IMA), vitamin C (VIT C), superoxide dismutase (SOD) and catalase (CAT). RESULTS Serum PCO (p < 0.001), plasma TBARS (p < 0.01), serum IMA (p < 0.0001) levels, erythrocytes CAT (p < 0.001), and SOD activities (p < 0.05) were significantly higher in STEMI patients when compared with the control group (p < 0.001). No difference in the IMA levels and oxidative stress parameters was observed between conditions of AMI. Only plasma VIT C in STEMI patients was significantly lower when compared with NSTEMI patients and control group (p < 0.001). CONCLUSIONS Results suggest that the oxidative profile generated by STEMI and NSTEMI is similar regardless of the size of arterial occlusion generated by thrombus.

Abstract
ABSTRACT Solanum guaraniticum is a medicinal plant traditionally used to treat gastric and liver diseases. However, there is no documented evidence corroborating its safety. The present study evaluated the potential toxicity of S. guaraniticum leaf extract after acute administration in rats. Single doses of the extract (1.250, 2.500, and 5.000 mg/kg) were administered by gavage, and the rats were then monitored for 48 h and/or 14 days. Mortality, acute signs of toxicity, and general activity in the open field test were assessed as well as hematological and biochemical parameters, enzymatic activity (δ-aminolevulinate dehydratase and acetylcholinesterase), and oxidative stress parameters (lipid peroxidation level, non-protein thiol content, tissue catalase activity, and serum ferrous reducing power). Phytochemical analysis was also performed by HPLC. The results showed that extract administration produced no deaths (LD50 > 5,000 mg/kg), and no significant adverse effects regarding food consumption, body weight gain, gross pathology, or other parameters. However, the open field tests showed a decrease in spontaneous activity (crossing and rearing) mainly at 48 h after treatment. The results suggest that S. guaraniticum extract is not acutely toxic, but causes alterations in central nervous system activity.

Abstract
OBJECTIVE This study aimed to investigate the effect of the leaf extracts of Syzygium jambos and Solanum guaraniticum on the δ-aminolevulinate dehydratase (δ-ALA-D) activity, their antioxidant activity and potential protective action on oxidatively stressed erythrocytes, in order to demonstrate the safety or toxicity of the plant. METHODS In erythrocyte samples, the effect of both extracts on δ-ALA-D activity, H2O2-induced oxidative stress, and 2,2'azobis (2-amidinopropane) (AAPH)-induced hemolysis was evaluated, as well as some antioxidant mechanisms. RESULTS Both extracts inhibited δ-ALA-D activity (S. guaraniticum > S. jambos), and an involvement of the zinc ion of the δ-ALA-D structure on the inhibition of enzyme activity was verified. S. jambos leaf extract showed marked efficiency in countering H2O2-induced lipid peroxidation and in maintaining cellular integrity against AAPH-induced hemolysis. Furthermore, S. jambos exhibited greater H2O2 scavenging activity and stronger reduction power than S. guaraniticum. DISCUSSION Both extracts bear potent antioxidant property as an important beneficial effect. However, the inhibition of δ-ALA-D activity suggests a possible harmful effect of these vegetal preparations and indicates the need for further investigation regarding their toxicological properties. All together, these data represent a significant contribution to the knowledge of these plants, both to the scientific community and to the folk medicine.

Abstract
AIMS To assess the effect of hypertension on δ-aminolevulinate dehydratase (δ-ALA-D) activity of type 2 diabetic patients (T2DM). METHODS δ-ALA-D activity and reactivation index, as well as markers of oxidative stress, biochemical and anthropometrics parameters were determined in T2DM (n=23), type 2 diabetic patients with hypertension (T2DM/HT) (n=30) and controls (n=30). RESULTS T2DM/HT presented a greater inhibition of δ-ALA-D activity, a higher reactivation index (p<0.05) and a greater depletion of plasma protein thiol groups (P-SH) when compared to T2DM. Moreover, δ-ALA-D activity was positively associated with SH groups and negatively associated with serum protein carbonyl (PC) while its reactivation index was negatively associated with SH groups and positively associated with PC. CONCLUSIONS These results point out that there is a possible interference of hypertension on the mechanism of the δ-ALA-D activity suggesting that this condition aggravated the oxidative stress of diabetes mellitus.
