Hypertrophic scars can occur anywhere on skin after a skin injury or wound. The reason is not fully understood, the result is the abnormal production of extra collagen and a decrease in elastin, which lead to these undesirable thick, raised stiff scars. Sometimes surgery is performed to cut out the scar or redirect the lines of tension on the scar. Usually, surgery is considered when other treatment options have failed. Dermacell is human acellular matrix (hADM) that is intended for supplemental support and covering for soft tissue repair. It acts as ECM. The expression and proliferation of extracellular matrix (ECM) molecules in the dermis, mediated by a range of growth factors and cytokines, is a fundamental element of wound repair.

There are occurrences of the Pantophthalmidae Family in several Brazilian states, in which observed the habits of these insects. It appears that the larvae are more active at night, live in living or dead trees, and they feed on accumulated organic matter or the products of wood fermentation, on the other hand, adult activities are restricted to reproduction, being cuddles and showing sexual dimorphism. The aim of this paper is to study the biological and taxonomic aspects of the Pantophthalmidae Family. For this, a bibliographic survey of Pantophthalmidae was carried out in the years 1976 to 2022. Only complete articles published in scientific journals and expanded abstracts presented in national and international scientific events were considered. Data were also obtained from platforms such as: Academia.edu, Frontiers, Qeios, Pubmed, Biological Abstract, Publons, Dialnet, World, Wide Science, Springer, RefSeek, Microsoft Academic and Scienc.
在巴西的几个州发现了这些昆虫的习性。幼虫在夜间活动较多，生活在活树或死树中，以积累的有机物或木材发酵的产物为食，成虫的活动则局限于繁殖、拥抱和两性二态性。本文的目的是研究泛眼蝇科的生物学和分类学方面。为此，在1976年至2022年期间对Pantophthalmidae进行了书目调查。只考虑在科学期刊上发表的完整文章和在国家和国际科学活动上发表的扩展摘要。数据还从以下平台获得:Academia.edu、Frontiers、Qeios、Pubmed、Biological Abstract、Publons、Dialnet、World、Wide Science、Springer、RefSeek、Microsoft Academic and Science。

The aim of this paper is to study the effect of fruit thinning and some fruit and cladode components on fruit growth and weight of cactus pear Opuntia ficus-indica (L.) Mill. The relationships between the fruit fresh weight and each of the parameters number of fruits per cladode, surface of cladodes and the dry weight of cladodes are studied. Experiments were carried out on an adult plantation of cactus pear in the Agadir area. Fruit thinning treatments used were: T: control without thinning, T1: thinning treatment of 6 fruits per cladode and T2: thinning treatment of 12 fruits per cladode. The size of cladodes used are: the small cladodes (C1), the medium cladodes (C2) and the large cladodes (C3). Obtained results showed that fruit thinning and the surface of cladodes and the interaction of the two factors have a significant effect (p ≤ 0.001) on fruit growth. On May 10, 2019, the highest rate of growth was obtained with the combination T1/C3 (thinning treatment T1 and large cladodes C3), with 1.6 cm for fruit length and 1 cm for fruit diameter, and the lowest rate of growth was obtained with the combination C1/T (not thinned plants and small cladodes C1) with 0.5 cm for fruit length and 0.3 cm for fruit diameter. The ratio dry weight of cladodes/ number of fruits per cladode has a significant effect (p ≤ 0.001) on the fruit fresh weight. The increase in the dry weight of cladodes and the reduction in the number of fruits per cladode leads to the production of fruits with large size. Positive linear relationships exist between the fruit fresh weight and the ratio dry weight of cladodes/ number of fruits per cladode, between the fruit fresh weight and the number of fruits per cladode, and between the fruit fresh weight and the surface of cladodes and the coefficient of determination R2 for each linear relationship is close to 1.

Reproduction of gall wasps is partially by sexual reproduction and partially by parthenogenesis, where the male is completely unnecessary. As in many species, however, there is an alternation of generations with one to two sexual generations and one parthenogenetic generation annually. This process differentiates the various generations in their appearance and in the way they induce the galls. The larvae of many species develop gallant characteristics; and there are also many species that are tenants or parasites of other gall wasps, such as those of the genus Synergus. This mini review aims to verify the importance of Cynipidae Family ornamental and food plants. To this end, a bibliographic survey of Cynipidae was carried out in the years 1937 to 2021. Only complete articles published in scientific journals and expanded abstracts presented at national and international scientific events. Data were also obtained from platforms such as: Academia.edu, Frontiers, Qeios, Biological Abstract, Publons, Dialnet, World, Wide Science, Springer, RefSeek, Microsoft Academic and Science.
瘿蜂的繁殖部分是通过有性繁殖，部分是通过孤雌生殖，在这种情况下，雄性是完全不必要的。然而，在许多物种中，每年有一到两个有性繁殖的世代和一个孤雌繁殖的世代交替。这一过程区分了不同的世代在他们的外观和方式，他们诱发的胆汁。许多种类的幼虫发育出勇敢的特征;也有许多种是其他瘿蜂的租客或寄生虫，例如Synergus属的瘿蜂。本文综述了菊科观赏和食用植物的重要性。为此，在1937年至2021年期间进行了一项关于雪梨科的书目调查。只有在科学期刊上发表的完整文章和在国内和国际科学活动上发表的扩展摘要。数据还从以下平台获得:Academia.edu、Frontiers、Qeios、Biological Abstract、Publons、Dialnet、World、Wide Science、Springer、RefSeek、Microsoft Academic and Science。

Diapriidae are commonly found in moist and shady habitats, where they can be very diverse; despite its abundance, little is known about its biology. The basal diapriids, Belytinae and Ambositrinae are probably parasitoids of larvae or pupae of Mycetophilidae and Sciaridae (Diptera). Diapriinae are mostly Diptera parasitoids (Brachycera and Cyclorrhapha), some species parasitize staphylinid and scarab (Coleoptera) larvae others are associated with Formicidae (or with dipterans associated with ants. Some species of Diapriidae were used in biological control programs for dipterans. The purpose of this article is to obtain description of the Family (Insecta: Hymenoptera). In this article, the bionomy of the Diapriidae Family will be studied. To this end, a bibliographic survey of Ichneumonidae was carried out in the years 1940 to 2021. Only complete articles published in scientific journals and expanded abstracts presented at national and international scientific events, Doctoral Thesis and Master's Dissertation were considered. Data were also obtained from platforms such as: Academia.edu, Frontiers, Qeios, Pubmed, Biological Abstract, Publons, Dialnet, World, Wide Science, Springer, RefSeek, Microsoft Academic, Science and ERIC.

Polycystic ovary syndrome (PCOS), an endocrine disorder has been associated with low-grade inflammation based on increased levels of several inflammatory mediators. Aim of the study was to assess the inflammatory markers in women with PCOS and their correlation with each other. Various inflammatory markers, neutrophil/lymphocyte ratio, hsC-reactive protein and CRP albumin ratio were found to be increased in women with PCOS in the study. Early detection of raised levels of inflammatory markers may help early diagnosis of PCOS and prevent development of metabolic syndrome.

Intracystic papillary carcinoma (IPC) of the breast is a rare malignant tumour, found mainly but not exclusively in elderly women. IPC may be asymptomatic or presents with a palpable mass or blood-stained nipple discharge. Radiologic manifestations of IPC are not specific. On ultrasonography, it can be a pure cyst, a mixed image, or a solid mass. Histologic features of the tumor include cellular proliferations surrounding fibrovascular cores, with or without invasion. The mainstay of treatment is breast-conserving surgery or mastectomy. Sentinel node biopsy could be considered in invasive cases. Adjuvant radiotherapy and/or endocrine therapy is considered in appropriate cases. Through the observation of a 58-year-old patient, we report the epidemiological, clinical and radiological data of papillary breast carcinoma.

This study investigated the effect of Gongronema latifolium extract on aluminum chloride-induced sperm oxidative stress. Spermatozoa were obtained from the epidydimis and dispersed in a buffer consisting of tris-(hydroxymethyl)-aminomethane, citric acid anhydrous and D (−) fructose (TCF buffer) and incubated with Gongronema latifolium alone (0.8 mg/ml), AlCl3 alone (50 mM) and Gongronema latifolium (0.2 – 0.8 mg/ml) + AlCl3 (50 mM) repectively, for 3 h at 32 0C. We found that exposure to aluminum chloride alone led to significant increase in lipid peroxidation (LP) 14.41±1.18µM and protein carbonyl content 19.21±0.9nM, but significant decrease on glutathione content 5.32±3.11mM. When Gongronema latifolium was added in the incubation medium, it improved and protected spermatozoa against the harsh effect of AlCl3 on sperm cells. Bioactive compounds detected from GC-MS analysis also revealed the presence of squalene, ascorbic acid, gamma tocopherol, phthalic acid,carbazic acid amongst others. This study showed that Gongronema latifolium could protect spermatozoa against AlCl3 induced sperm damage.

Transfer RNA (tRNA) is widely believed to be one of the oldest, if not the oldest nucleic acid on Earth. Concurrently, ribozymes, RNA-only catalysts that perform many of the same functions as present-day protein enzymes, are also thought to be just as ancient. While the position has been posited that tRNA, nature’s chief aminoacylator of amino acids with the assistance of aminoacyl-tRNA synthetase (aaRS) protein enzymes, evolved from a self-aminoacylating ribozyme, no studies have been performed, to the best of this author’s knowledge, searching for nucleotide sequence correlation between the two; such correlation would indicate the conservation of part or all of such a ribozyme in modern-day tRNA. To that end, an in-silico study utilizing several databases was performed to search for a high percentage of highly conserved nucleotide sequences in archaea, believed to be the most ancient of organisms, with very successful results and their implications discussed here.
