Pakistan, like many other regions around the world, is experiencing the impacts of climate change, particularly in its northern region. These changes have adverse impacts on ecosystems and biodiversity. Herein, we have investigated future projections of temperature and precipitation trends for three periods historical (HT = 1975-2005), near-term (NT = 2010-2029), and mid-term (MT = 2030-2050) using climate model intercomparison projects along with global climate models (GCMs) including RCP4.

Biochar is widely acknowledged for its remarkable impact on soil conditioning. However, the influence of different sources of biochar, particularly anaerobic digested sludge biochar (ADBC) derived from anaerobic digested sludge and biochar derived from waste activated sludge, on alkaline soil remains largely unexplored. To address this knowledge gap, a comprehensive field experiment was conducted over a period of 180 days to investigate the effects of ADBC on slightly alkaline soil.

Article Synopsis
  • The maize crop faces significant threats from four major pest species during various larval stages, making manual identification and control challenging.
  • To address this, an automated system using different Convolutional Neural Network models was developed, focusing on classifying the larval stages of these pests, including the Asian corn borer and fall armyworm.
  • Among the models tested, Densenet121 with the Adam optimizer achieved the highest classification accuracy of 96.65%, and performed well in real field conditions, demonstrating a 90% accuracy in identifying pest instars, highlighting its potential for improving pest management strategies in agriculture.

Article Synopsis
  • - The study focused on the effectiveness of acrylamide-based bait, known for its high water absorption, in controlling subterranean termites attracted to moisture-rich wood.
  • - Results showed that acrylamide had a significant water absorption capacity (70.6%) and effectively attracted termites, with the highest attraction recorded for wood blocks made from Populus deltoides and mixtures containing neem leaves and walnut shells.
  • - Combining acrylamide with boric acid significantly reduced wood consumption by termites, indicating the potential for these baits to be a commercially viable option for termite management.

In the context of cancer heterogeneity, the synergistic action of next-generation sequencing (NGS) and CRISPR/Cas9 plays a promising role in the personalized treatment of cancer. NGS enables high-throughput genomic profiling of tumors and pinpoints specific mutations that primarily lead to cancer. Oncologists use this information obtained from NGS in the form of DNA profiling or RNA analysis to tailor precision strategies based on an individual's unique molecular signature.

Land use has a great impact on soil dynamics. The soils of various land use systems in Central Karakoram have been under immense pressure in the recent past due to certain anthropogenic activities such as land use practices and land use cover changes. These influences have an impact on the spatial distribution of metallic elements (MEs) in the soils of various land uses.

A 9-year-old premenarchal female presented to pediatric dermatology with a 6-month history of periodically tender, bilateral and symmetric axillary masses. Magnetic resonance imaging and subsequent surgical excision confirmed the diagnosis of bilateral accessory axillary breast tissue. Accessory axillary breast tissue is a rare condition seen most in pubertal, pregnant and breastfeeding women.

The mechanical properties of a defect-free laser melting (PBF-LB) deposit of an AISI 316L steel alloy were assessed by means of an instrumented indentation test (IIT), at both the macro- and nano-scales. The inherent non-equilibrium microstructure of the alloy was chemically homogenous and consisted of equiaxed grains and large-elongated grains (under the optical microscope) with irregular outlines composed of a much finer internal cell structure (under the scanning electron microscope). Berkovich and Vickers indenters were used to assess the indentation properties across individual grains (nano) and over multiple grains (macro), respectively.

Cyclopropanes are of great synthetic value in heterocyclic chemistry due to their highly reactive nature. They are widely employed to synthesize various biologically active organic compounds. Generally, vinyl, carbonyl, imine, and alkylidene cyclopropanes are utilized as efficient synthetic precursors in organic synthesis.

Piperazine is a privileged moiety that is a structural part of many clinical drugs. Piperazine-based scaffolds have attracted the attention of pharmaceutical and medicinal scientists to develop novel, efficient therapeutic agents owing to their significant and promising biological profile. In the current study, an ecofriendly ultrasonic-assisted synthetic approach was applied to achieve a novel series of 1-tosyl piperazine dithiocarbamate acetamide hybrids - which was evaluated for in vitro tyrosinase inhibition and thrombolytic and hemolytic cytotoxic activities.

Terrestrial ecosystems are under the enormous pressure of land use management regimes through human disturbances, resulting in the disruption of biogeochemical cycles and associated ecosystem services. Nitrogen (N) in soil ecosystems is of vital importance for primary productivity, hence estimating the extent of these human interventions on N-cycling processes becomes imperative from economic and environmental perspectives. This work investigated the impacts of variable anthropogenic activities on N cycling in three different terrestrial ecosystems (arable, grassland, and forest) in three regions of lower Himalaya, Pakistan.

The Asian corn borer (Ostrinia furnacalis, Lepidoptera, Crambidae) and Oriental armyworm (Mythimna separata, Lepidoptera, Noctuidae) are 2 major lepidopteran pests of the maize plant, especially the whorls and tassels. The aim of this study was to investigate competition between 2 lepidopteran pests of maize. Intraspecific and interspecific competition occurs when O.

Graphene quantum dots (GQDs), a new solid-state electron transfer material was anchored to nitrogen-doped TiO via sol gel method. The introduction of GQDs effectively extended light absorption of TiO from UV to visible region. GQD-N-TiO demonstrated lower PL intensity at excitation wavelengths of 320 to 450 nm confirming enhanced exciton lifespan.

Article Synopsis
  • - Squamoid eccrine ductal carcinoma (SEDC) is a rare and underrecognized sweat gland cancer that poses risks for local recurrence and metastasis, with a distinct biphasic differentiation pattern resembling well-differentiated cutaneous squamous cell carcinoma (cSCC) and infiltrative ductal specificity.
  • - Diagnosis relies solely on histopathologic examination, and while its development remains poorly understood, a genetic analysis through whole-exome sequencing has identified multiple mutations that overlap with those found in cSCC but differ from other sweat gland cancers.
  • - The findings suggest that SEDC may start as a well-differentiated cSCC before evolving into a sweat gland-like tumor, highlighting the need for

  • * The distinction between low-grade and high-grade dysplastic nevi is often based on subjective criteria; this study aimed to see if follicular extension varies between the two grades.
  • * The analysis of 90 cases showed that both low-grade and high-grade dysplastic nevi had similar patterns of follicular extension, suggesting they may not differ significantly in this regard, indicating a need for further research.

Some have proposed that melanomas in situ may be associated with fields of melanocytic dysplasia, particularly on sun-damaged skin, whereas others maintain that the atypical junctional melanocytic hyperplasia (MH) at the periphery of melanomas is simply background junctional MH of sun-damaged skin. The biological potential of atypical junctional MH at the periphery of melanomas is uncertain. We examined whether atypical junctional MH was intrinsic to the melanoma itself (ie, melanoma-associated field of melanocytic dysplasia) or was simply the predictable junctional MH associated with long-standing sun exposure.
