Microscopic, histochemical and preliminary phytochemical characterization of leaves of Trema micrantha (L.) Blume

Para enriquecer el enriquecer el conocimiento sobre Trema micrantha (L.) Blume, esta investigación tuvo como objetivo realizar la caracterización anatómica, histoquímica y fitoquímica de las hojas de la especie. Se realizaron cortes transversales del pecíolo y limbo, así como cortes paradérmicos del limbo, analizados en microscopía óptica y polarizada. Se utilizaron diferentes reactivos para el análisis histoquímico. Se han descrito estructuras anatómicas que proporcionan un diagnóstico detallado de las especies estudiadas. La histoquímica mostró la presencia de metabolitos esenciales (flavonoides, taninos, entre otros) para la especie y mediante análisis SEM-EDS se confirmó que los cristales están compuestos por oxalato de calcio. El análisis fitoquímico permitió la identificación de mono y sesquiterpenos, triterpenos y esteroides, entre otros. El estudio proporcionó datos sin precedentes sobre la especie, ampliando la información científica de T. micrantha. In order to enrich the knowledge about Trema micrantha (L.) Blume, this research aims to perform the anatomical, histochemical and phytochemical characterization of the leaves of this species. Cross sections of the petiole and limbus were made, as well as paradermic sections of the limbus, analyzed in optical and polarized microscopy. Different reagents were used for histochemical analysis. Anatomical structures have been described and provide a detailed diagnosis of the species studied. Histochemistry showed the presence of essential metabolites (flavonoids, tannins, among others) for the species and through SEM-EDS analysis it was confirmed that the crystals are composed of calcium oxalate. Phytochemical analysis allowed the identification of mono and sesquiterpenes, triterpenes and steroids, among others. The study provided unprecedented data on the species, expanding the scientific information of T. micrantha.

A Novel Deep Learning Pipeline Architecture based on CNN to Detect Covid-19 in Chest X-ray Images

Covid-19 is a severe public health problem worldwide. To date, it has spanned worldwide, with 24.6 million infected with 835,843 confirm the death. Covid-19 detection is indeed an important task and has to be done as quickly as possible so that treatment and monitoring can be carried out early. The current world standard RT-PCR screening for Covid-19 detection has to cope with the world population's great demand. There is a need to have an alternative way to cope with the demands. It has to be a quick and accurate detection procedure, such as using a chest x-ray for Covid-19 detection. This paper proposes a deep learning pipeline architecture called Gray Level Co-occurrence Matrix GLCM) with Convolutional Neural Network (CNN) for Covid-19 detection using chest X-ray image. The proposed method has two main diagnosis features, a quicker diagnosis, and a detailed diagnosis. The quicker diagnosis uses few GLCM features and a standard neural network (NN) algorithm to detect Covid-19 symptoms. It is a suitable method for rural areas where computing resources are minimal. The detailed diagnosis uses huge image pixel features and a deep convolutional neural network (CNN) algorithm to detect Covid-19 symptoms. It is a suitable method for places where computing resources are sufficient. The proposed work provides the highest classification performance, with 97.06% accuracy compared to other similar works.

On the identity of Lepidodexia (Orosarcophaga) ornata (Townsend, 1927) (Diptera: Sarcophagidae) and a new generic synonym

The revision of the sarcophagid species Lepidodexia (Orosarcophaga) ornata (Townsend, 1927) reveals its identity and a generic synonym. The male terminalia of this species was studied in detail for the first time and revealed its congeneric affinities with Oxyvinia Dodge, 1966. Consequently, the generic status of Orosarcophaga Townsend, 1927 was revalidated, including Oxyvinia Dodge, 1966 as its junior synonym, and O. ornata was corroborated as a valid species and name. Moreover, we provide an updated generic diagnosis of Orosarcophaga, a list of the eleven species of the genus with their distribution, and a detailed diagnosis of O. ornata.

Novelties on Lippia sect. Goniostachyum (Verbenaceae): a new variety from the Brazilian Cerrado and additional nomenclatural and taxonomic notes

Lippia stachyoides var. guajajarana, a new variety of Verbenaceae endemic from the Emas National Park, Goiás State, is described and illustrated. The new variety belongs to L. sect. Goniostachyum, which is characterized by numerous florescences per leaf axil and tetrastichous floral bracts. A detailed diagnosis, comparison with morphologically similar taxa, a key to the species and varieties from the section, plus habitat information, illustration, and a conservation status assessment are provided. Furthermore, L. morii is included in L. sect. Goniostachyum based on morphological traits and L. rivalis is considered a new synonym of L. origanoides. Lectotypes are designated for L. morii and L. rivalis, contributing to the taxonomy and nomenclature of the section.

Cave-dwelling pseudoscorpions of China with descriptions of four new hypogean species of Parobisium (Pseudoscorpiones, Neobisiidae) from Guizhou Province

We summarize and discuss the 29 known cave-dwelling pseudoscorpion species from China. Four new troglomorphic pseudoscorpion species, Parobisium motianensesp. nov., P. qiangzhuangsp. nov., P. sanlouensesp. nov., and P. tianisp. nov., belonging to the family Neobisiidae, are described based on specimens collected in karst caves in Guizhou, China. Detailed diagnosis, descriptions, and illustrations are presented. We also provide recommendations for management of caves where they occur, as well as the cave arthropod communities and the habitats that support them.

Techniques for Lung Cancer Detection from CT Image

The most lethal disease found in the medical field is lung cancer and early detection of this disease has become a challenge for many doctors and diagnostics. The lung cancer contributes over 15.3% of the total number of new cases diagnosed in the recent years. Smoking and pollution are considered as the major causes of lung cancer. At present, there are huge number of tests available to detect lung cancer such as PET Scan, Computerized Tomography (CT) Scan and X-ray etc. are used to diagnose the disease. By x-ray the picture of the lungs may uncover the unusual mass or nodule. A further developed adaption found in CT scan which can uncover the small lesions in the lung that probably won’t be distinguished with X-ray. Biopsy tests are done for detailed diagnosis of the disease. For accurate and better results, a data mining techniques, machine learning algorithms or deep learning algorithms could be used in the laboratories. In this survey, we have elaborated various existing techniques used so far.

The generic nomenclature of the Trochilini: a correction

Because the generic name Elliotia proposed by us (Stiles et al. 2017a) was found to be preoccupied, we herein rename this genus, including a detailed diagnosis; the generic circumscription and type species remain unchanged. This change does not affect the generic reorganization of the Trochilini presented by Stiles et al. (2017a).

Duodenogastric refluх: a look at the problem in terms of carcinogenesis

The role of duodenogastric reflux (DGR) in malignant degeneration of the gastric mucosa. It was demonstrated by immunohistochemistry using monoclonal antibodies to p53, PCNA, CD10, MUC2, MUC5AC, MUC6, CD31 and the polymerase chain reaction to detect CDX1, CDX2, FXR genes. The main carcinogenic components of bile are lysolecithin and conjugated bile acids. Biliary reflux increases the risk of malignant tumors in combination with Helicobacter pylori. DGR is one of the etiological factors for gastric cancer, so it determines the necessity for detailed diagnosis in clinical practice.
