Plants of the genus Brassica occupy the top place among vegetables in the world. This genus, which contains a group of six related species of a global economic significance, three of which are ...diploid: Brassica nigra (L.) K. Koch, Brassica oleracea L., and Brassica rapa L. and three are amphidiploid species: Brassica carinata A. Braun, Brassica juncea (L.) Czern., and Brassica napus L. These varieties are divided into oily, fodder, spice, and vegetable based on their morphological structure, chemical composition, and usefulness of plant organs. The present review provides information about habitat, phytochemical composition, and the bioactive potential of Brassica plants, mainly antioxidant, antimicrobial, anticancer activities, and clinical studies in human. Brassica vegetables are of great economic importance around the world. At present, Brassica plants are grown together with cereals and form the basis of global food supplies. They are distinguished by high nutritional properties from other vegetable plants, such as low fat and protein content and high value of vitamins, fibers along with minerals. In addition, they possess several phenolic compounds and have a unique type of compounds namely glucosinolates that differentiate these crops from other vegetables. These compounds are also responsible for numerous biological activities to the genus Brassica as described in this review.
In this study, we investigated the formation of protein–phenolic complexes from dephenolized hazelnut meal protein isolates (dHPI) and hazelnut skin phenolic extracts (HSE) and their effects on the ...bioaccessibility of both hazelnut proteins and phenolics. The dHPI–HSE complexes were of considerable size and were dependent on HSE concentration due to aggregation. Although catechin was the main component of HSE, it did not cause aggregation, except for a slight rise in particle size. According to fluorescence quenching, the hazelnut protein–phenolic extract complex had a linear Stern–Volmer plot expressing static quenching between 0–0.5 mM concentration; the interaction was mainly dependent on hydrogen bonding and van der Waals forces (ΔH < 0 and ΔS < 0), and the reaction was spontaneous (ΔG < 0). According to Fourier transform infrared (FTIR) spectroscopy results, higher phenolic extract concentration caused an increase in irregular structures in hazelnut protein, while the lowest catechin and phenolic concentration altered the regular structure. Skin extracts did not alter the digestibility of dephenolized proteins, but dephenolization reduced the degree of hydrolysis by pancreatin. The formation of the protein–phenolic complex had a beneficial effect on the bioaccessibility of hazelnut skin phenols, predominantly those on the galloylated form of the catechins, such as gallocatechin gallate and epigallocatechin gallate. Thus, the bioaccessibility and antioxidant activity analysis results showed that protein–phenolic complexes obtained from hazelnut meal and skin may promote the transition of phenolic compounds from the gastrointestinal tract without degradation.
Human beings exist in a biological and social system from a micro to a macro level, by means of “collectivity”, a dynamic collaboration that they have established together with the elements in that ...system in a way to complement each other and realize a common goal. Many neuroscientific concepts used today to explain neuronal processes from which mental functions originate are far from searching answers to traditional philosophical questions. However, the brain — as the generator of highly abstract concepts — is so complex that it cannot be explained by minimalistic approaches. The concept of connectome used in recent years to describe neuronal connections from which brain functions originate exemplifies this minimalistic approach, because it only describes structural and functional connections but does not look at brain functions in a holistic view. For this reason, we propose the concept of collectome — to replace the concept of connectome — that describes a homeomorphic and homotopic neuronal framework that has a bicontinuous style of work from micro to macroscale which is based on fractal rules.

The current diagnostic classification systems in psychiatry have been developed primarily for evidence-based clinical decision making with both categorical and dimensional approaches having their own ...advantages and disadvantages. Efforts have been made to improve these classification systems, and we are now at the point where we must expand beyond the one-dimensionality of these systems. In this paper, we propose that psychiatric disorders can be arranged in a three-dimensional classification system according to the degree of dysfunctions on three specific axes in a way that is similar to the arrangement of chemical elements according to their atomic weights in Mendeleyev’s periodic table. For the three axes, we chose externalization, drive, and attention to represent the three-dimensional descriptions of mental health, namely, well-being in social, motivational, and cognitive areas, respectively. Throughout the paper, we explain our reasons for choosing these three axes and compare our hypothesis with categorical diagnostic systems as well as Cloninger’s dimensional diagnostic system using personality disorders, affective disorders, and schizophrenia as the specific diagnostic samples.
Angiotensin-converting enzyme 2 (ACE2) is a host receptor for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Inhibiting the interaction between the envelope spike glycoproteins ...(S-proteins) of SARS-CoV-2 and ACE2 is a potential antiviral therapeutic approach, but little is known about how dietary compounds interact with ACE2. The objective of this study was to determine if flavonoids and other polyphenols with B-ring 3′,4′-hydroxylation inhibit recombinant human (rh)ACE2 activity. rhACE2 activity was assessed with the fluorogenic substrate Mca-APK(Dnp). Polyphenols reduced rhACE2 activity by 15–66% at 10 μM. Rutin, quercetin-3-O-glucoside, tamarixetin, and 3,4-dihydroxyphenylacetic acid inhibited rhACE2 activity by 42–48%. Quercetin was the most potent rhACE2 inhibitor among the polyphenols tested, with an IC50 of 4.48 μM. Thus, quercetin, its metabolites, and polyphenols with 3′,4′-hydroxylation inhibited rhACE2 activity at physiologically relevant concentrations in vitro.
This paper is an effort to describe, in neuroscientific terms, one of the most ambiguous concepts of the universe—the soul. Previous efforts to understand what the soul is and where it may exist have ...accepted the soul as a subjective and individual entity. We will make two additions to this view: (1) The soul is a result of uninhibited mental activity and lacks spatial and temporal information; (2) The soul is an undivided whole and, to become divided, the soul has to be reduced into unconscious and conscious mental events. This reduction process parallels the maturation of the frontal cortex and GABA becoming the main inhibitory neurotransmitter. As examples of uninhibited mental activity, we will discuss the perceptual differences of a newborn, individuals undergoing dissociation, and individuals induced by psychedelic drugs. Then, we will explain the similarities between the structure of the universe and the structure of the brain, and we propose that consideration of the rules of quantum physics is necessary to understand how the soul is reduced into consciousness.
Propolis is a resinous bee hive product that has many biological activities. In this study, a total of 11 raw propolis samples were collected from various geographical areas in Turkey. Phenolic ...compounds were extracted from all samples and analyses of total phenolics and flavonoids and total antioxidant capacities were performed. All the samples showed high total phenolic and flavonoid contents and antioxidant capacities. Moreover, the in vitro bioaccessibility of Turkish propolis samples were investigated according to simulated in vitro gastrointestinal digestion method. Bioaccessibility was increased through the gastric and intestinal phases. Furthermore, the composition of polyphenols (phenolic acids and flavonoids) in Turkish propolis extracts was investigated by LC-MS/MS method. A total of 32 phenolic compounds, including Caffeic acid phenylethyl ester (CAPE) which was observed in all samples, were identified in the samples. Higher CAPE contents were determined in the samples from the Marmara region which is in line with its higher antioxidant capacity values. As a conclusion, propolis samples collected from different geographical locations differ for their phenolic and flavonoid contents, individual phenolic profile and bioaccessibility.
