In Saudi Arabia, approximately one-third of colorectal cancer (CRC) patients are diagnosed at an advanced stage. Late diagnosis is often associated with a worse prognosis. Understanding the risk factors for latestage presentation of CRC is crucial for developing targeted interventions enabling earlier detection and improved patient outcomes.

Esophageal carcinoma is a type of cancer that occurs in the esophagus. For patients with locally advanced or metastatic esophageal squamous cell carcinoma who have either experienced disease progression following first-line standard chemotherapy or are intolerant to it, the prognosis is typically poor.

The paper "A novel approach of neural networks and USLE in smart soil erosion modeling, case study in Southern coastal of Viet Nam" adopted one of the neural networks - the Long ShortTerm Memory (LSTM) to analyze temporal variations in erosion patterns over time, aiding in understanding erosion dynamics. Furthermore, another common soil erosion model - the Universal Soil Loss Equation (USLE) was investigated to predict annual soil loss. Our data were extracted from remotely sensed data (DEM - Digital Elevation Model and MODIS) and vector data of the study area.

Ebook "Morphometrics with R" aims to explain how to use R to perform morphometrics. Morpho- tric analysis is the study of shape and size variations and covariations and their covariations with other variables. Morphometrics is thus deeply rooted within stat- tical sciences. While most applications concern biology, morphometrics is becoming common tools used in archeological, palaeontological, geographical, or medicine disciplines.

The distribution of lymphoma subtypes differs strikingly by geographic variations. However, there is limited information on this research in northern Iran. This study aims to evaluate the incidence, subtype, age, sex, and extranodal distribution of lymphomas diagnosed according to the latest WHO classification in a large referral center in northwest Iran.

To examine experiences of racial discrimination among Asian Americans, which broadly contribute to poor health outcomes. We calculated the percent of Asian Americans reporting discrimination in several domains, including health care. We used logistic regression to compare the Asian-white difference in odds of discrimination, and among Asians only to examine variation by geographic heritage group (South Asian versus East Asian) and gender.

Breonadia salicina (Rubiaceae) is a critically endangered plant at the local scale native to southwestern Saudi Arabia. To understand the levels and partitioning of genetic variation across populations and geographical regions of this species, we assessed its genetic diversity using inter-simple sequence repeat (ISSR) markers.

Much of the data resolution of the haploid non-recombining Y chromosome (NRY) haplogroup O in East Asia are still rudimentary and could be an explanatory factor for current debates on the settlement history of Island Southeast Asia (ISEA). Here, 81 slowly evolving markers (mostly SNPs) and 17 Y-chromosomal short tandem repeats were used to achieve higher level molecular resolution.

Dung beetles are widely used as bio-indicators of habitat changes because they respond quickly to changes in environmental conditions. Altitudinal variation in dung-beetle communities has been studied in various geographical areas. However, there is little known about dung-beetle shifting in tropical forests of Vietnam.

Geographical disparities in cancer incidence are observed at different scales and may highlight areas of high risk that need special attention to improve health policies. In Guadeloupe, a French archipelago in the Carib‑ bean, environmental and socioeconomic factors are potential factors associated with cancer incidence.

Afrolaophonte pori was originally described from the interstitial habitats of Israel and subsequently reported from Italy and the Aegean coasts of Turkey. It is the only representative of the genus in the Mediterranean Sea. The aim of this study is to present a detailed redescription of A. pori based on extensive material from different parts of the species’ range to provide geographic distributional data and to reveal variations within and between the populations.

Ecologists use various data mining techniques to make predictions and estimations, to identify patterns in datasets and relationships between qualitative and quantitative variables, or to classify variables. The aim of this study was to investigate if the application of data mining could be used to study geographical variation in the morphometry, craniometry, and diet of a mammalian species (Martes foina), and to determine whether data mining can complement genetic analysis to recognize subspecies.

Brachypodium distachyon (L.) P.Beauv. is a model grass species that is useful for studying temperate cereal, forage, and energy crops. In this study we aimed to determine the genome size and species identity in the collections of the B. distachyon complex that included samples from 56 different locations in Turkey, applying chromosome counting and nuclear genome size evaluation by flow cytometry method (FCM). Moreover, the study examined whether diverse geographical conditions at the collecting sites influence the genome size. Chromosomal analysis revealed that the number of B.
