Using biostimulants in plant cultivation can increase plant growth and make plants more stress-resistant. Plant extracts are one source of natural biostimulants such as Moringa (Moringa oleifera L.), which contain secondary metabolites and plant growth hormones. In the process of plant extraction, the type of solvent used affects the quality of the resulting extract. This study aimed to determine the effect of biostimulants of Moringa leaf extract extracted with several types of solvents on the growth of red spinach (Amaranthus tricolor L.)  This research was conducted from March to April 2022 in the Greenhouse and Plant Physiology Laboratory, Department of Biology, Faculty of Mathematics and Natural Sciences, Universitas Andalas, Padang. This study used a Completely Randomized Design (CRD) with four treatments and eight replicates. As treatment is a solvent for extracting moringa leaves consisting of without extract (A), Distilled water (B), Methanol (C), and Ethanol (D). The results showed that the solvent used to extract moringa leaves gave a significantly different effect on the number of leaves but had no significant effect on plant height, leaf area, root length, wet weight, dry weight, chlorophyll content, and anthocyanin content of red spinach plants. Extraction of moringa leaves with methanol and ethanol increases the number of red spinach leaves, which is  14.1 strands.

The Clinical Manifestation of Primary Progressive Aphasia
Authors: Mathew Chris
Published: July 2023

This review mainly focuses on language disorders. One type of language disorder is known as aphasia. Aphasia is generally occurring due to secondary lesions that appear on subcortical white matter that injures the left hemisphere and hence causes dysfunction in linguistic information such as grammar, syntax, morphology, semantics and other aspects of language. Aphasia is considered an acquired language disorder as it blocks the language usage as a whole. Aphasia can be of primary and secondary. Primary aphasia deals with problems associated with language mechanisms whereas secondary aphasia deals with problems associated from memory, attention and perceptual impairment. Primary progressive aphasia also abbreviated as PPA, is a neurodegenerative disorder that is closely associated with any form of cerebrovascular accident such as stroke, cerebral tumours and brain injury that affects the middle cerebral artery and its branches. Primary progressive aphasia also tends to form when there is family history and 2-3 siblings receive it. It is led to believe that people inherit PPA due to the mutation of a particular gene known as progranulin on chromosome 17q21.31. While progranulin gene is mutated, a hyperphosphorylated protein is deposited in brain known as tau in the form of intraneuronal neurofibrillary tangles or otherwise known as pick bodies.
Biochemical Inspiration from Chomsky’s “Reflections on Language”
Authors: Marx Gerard
Published: July 2023

The biochemical basis of psychology and memory remain obscure. Psycho- and linguistic- analysis provide few clues regarding the processes that occur in our heads. Here, I try to give an autobiographical account of the development of a scientific idea of how a mental process such as memory, can be encoded in the brain. My story began (~1980) with an account of how I started as a research biochemist working in blood coagulation, then became inspired by remarks in a book on linguistics (Noam Chomsky), to quote: • “Since the subject is a physical organism, the system attributed to it must have finite representations.” • “Symbol systems that fit different molds also have different neural representations…different physical representations.” • “An empirical argument must be brought to bear.” I formulated the concept of a “cation array” as the basis for the biochemical coding of information processing in the brain, as required for memory. The core idea was that the neuron employs various elemental cations (Zn+2, Cu+2, Mn+2, etc) to encode experience into the surrounding neural extracellular matrix (nECM). The nECM serves as an chemo- lectric lattice, wherein neurons manipulate multiple trace metals (n>10) to encode, store and recall cognitive information. Energy requirements are low, rates are high, and encoding capacity is enormous. I submitted manuscripts to various journals but was rejected by all. Discouraged, I put aside this work for more than 30 years. In the interim, I continued to experimentally examine the effects of elemental cations on blood coagulation with fair success in terms of publishing the unique modulating effects of physiologic levels of Zn+2, Cu+2 on blood coagulation. After > 30 years of lying fallow, the concept of a “cation array” became revitalised by a collaboration with a fellow biochemist (Chaim Gilon, Hebrew University). Because of weekly meetings (which were videotaped), we developed of a tripartite mechanism for memory which addressed many of the points raised by Chomsky. We articulated and chemographically described a tripartite mechanism for memory, whereby a chemically based code for cognitive information permits the achievement of an emotive state instigated by metals and neurotransmitters (NTs) released by neurons/glial cells. Thus, we link biochemical processes available to neural nets to the achievement of psychic states, including memory, emotions and consciousness. The evolution of this idea continues and we invite others to join our efforts to dis-entangle psychology with physiological biochemistry.

The following essay proposes within the theoretical revision of Lacan's text "Paranoid psychosis in its relations with personality" framing the position of the French psychoanalyst regarding the disorder and elucidating some proposals on how to understand the condition and the importance of understanding it from a look that borders on philosophy, history and above all the contextual history of the patient presented in the text. It is necessary to consider the need to make a review since even with the time that precedes the text at the time of reading we realize how current the case can represent.
Mental Health Therapy: Multivitamins
Authors: Dudi Ashok Kumar
Published: July 2023

Aims and Objectives: This study promotes mental health multivitamin supplementation as an alternate treatment. Methodology: Complementary therapy of multivitamin supplementation is designed using introspection and Google Scholar. Research and Results: Nutritional deficiencies can affect the brain and neurological system. Oxidative stress damage DNA, proteins, dendrites, and mitochondria. Mental health is linked to gut-environment impacts via the brain-gut axis. Serotonin, GABA, epinephrine, norepinephrine, and dopaminergic pathways can be affected by psychiatric dietary therapy. N- cetylcystine (NAC), coenzyme Q10, and NAD+ may treat neurological and neuroprogressive illnesses. Retinoic acid induce embryonic stem cell neural lineage differentiation, which can damage adult hippocampal neurogenesis (AHN) and mental health. Multivitamins support brain and body function. Conclusion: Psychiatric problems can be healed with multivitamins.
Rethinking a Danish information state: information in the trading zone
Authors: Skouvig Laura
Published: July 2023

In this article, I will discuss how the information state provides a new way of understanding the absolute Danish-Norwegian state (1660–1814). Following recent research about the role of communication in the Danish-Norwegian state, I will argue for an understanding of the information state that stresses the population as a formative part of state building. The studies favour a communicative approach, which includes circulation of information as an integral part. My contribution to the discussion of the information state emphasises that exchange of information between state and population implies negotiations and the use of genre systems in a trading zone. The meeting between ideology and everyday practices and cultures is a negotiation that shows how ideologies, purposes, and ideas are sifted and negotiated through concrete practices that are formed by but also shape technologies and materialities.

On Solé and Planat Criterion for the Riemann Hypothesis
Authors: Vega Frank
Published: July 2023

There are several statements equivalent to the famous Riemann hypothesis. In 2011, Solé and Planat stated that the Riemann hypothesis is true if and only if the inequality $\zeta(2) \cdot \prod_{q\leq q_{n}} (1+\frac{1}{q}) > e^{\gamma} \cdot \log \theta(q_{n})$ holds for all prime numbers $q_{n}> 3$, where $\theta(x)$ is the Chebyshev function, $\gamma \approx 0.57721$ is the Euler-Mascheroni constant, $\zeta(x)$ is the Riemann zeta function and $\log$ is the natural logarithm. In this note, using Solé and Planat criterion, we prove that the Riemann hypothesis is true.
