RESUMEN
Immunoglobulin G4-related disease (IgG4-RD) is a systemic fibroinflammatory condition characterized by significant infiltration of immunoglobulin G4 (IgG4)-positive plasma cells within affected tissues, with or without elevated serum IgG4 levels. The prevalence of IgG4-RD remains largely undetermined due to diagnostic challenges, as the condition is frequently unrecognized or misdiagnosed. This report describes a case of a 63-year-old man who was ultimately diagnosed with this rare condition after an extensive two-year period of elusive symptoms. Initially presenting with intermittent body pains and fluctuating fever, his condition progressively evolved to include severe right orbital swelling with marked tenderness and ecchymosis, recurrent non-tender nodules on his arm, and diminished vision. A detailed review of his medical history prompted the consideration of IgG4-RD, leading to the measurement of serum human IgG4 levels, which were found to be significantly elevated at 1504 mg/L (normal range: 39.2-864 mg/L). Following his diagnosis, treatment with glucocorticoids (0.6 mg/kg for one month) was initiated, resulting in a positive clinical response. This case emphasizes the critical importance of considering less common conditions in the differential diagnosis of patients presenting with complex, multi-system symptoms.
RESUMEN
In this study, we sequenced, assembled and reported the complete chloroplast genome of Lantana camara an important medicinal plant for the first time. The genome is circular and quadripartite in structure; it has a length of 154,388 bp, 39.2% GC content and harbored 137 genes including 90 protein-coding genes, 39 tRNAs, and 8 rRNAs. The genome contained a large single-copy of 85,198 bp and a small single-copy of 17,249 bp separated by a pair of inverted repeat regions. The phylogenetic relationship showed a close relationship between L. camara and Lippia origanoides. The plastome sequence reported in this study will help for future research on the species and evolutionary studies of Verbenaceae.
RESUMEN
Lantana camara L. is an economically important essential oil producing plant belonging to family Verbenaceae. It is used in medication for treating various diseases like cancer, ulcers, tumor, asthma and fever. The plant is a useful source of essential bioactive compounds such as steroids, flavonoids and phenylpropanoid glycosides etc. Nonetheless, very little is known about the genomic or transcriptomic resources of L. camara, and this might be the reason of hindering molecular studies leading to identification of improved lines. Here we used Illumina sequencing platform and performed the L. camara leaf (LCL) and root (LCR) de novo transcriptome analyses. A total of 70,155,594 and 84,263,224 clean reads were obtained and de novo assembly generated 72,877 and 513,985 unigenes from leaf (LCL) and root (LCR) respectively. Furthermore, the pathway analysis revealed the presence of 229 and 943 genes involved in the phenylpropanoid biosynthesis in leaf and root tissues respectively. Similarity search was performed against publically available genome databases and best matches were found with Sesamum indicum (67.5%) that were much higher than that of Arabidopsis thaliana (3.9%). To the best of our knowledge, this is the first comprehensive transcriptomic analysis of leaf and root tissues of this non-model plant from family Verbenaceae and may serve as a baseline for further molecular studies.

Plants have evolved several metabolic pathways as a response to environmental stress like low temperatures. In this perspective, it is paramount to highlight physiological mechanisms of plant responses to changing environments. To determine the impact of cold stress on the physiological attributes of high altitude plant natives, i.e. Pedicularis punctata and Plantago major, we studied the protein, sugar and proline contents, as well as abscisic acid (ABA) and indoleacetic acid (IAA) in leaves collected from three different altitudinal ranges in Himalayan region of Pakistan. Leaves were collected at the initial blooming phase from each altitudinal range i.e. 2400-2500 m, 2950-3250 m and 3500-3550 m. Temperature decreases with an increase in the altitude which induces cold acclimation. Both plant species showed significant variation in the concentrations of the ecophysiological attributes evaluated at the different collection altitudes. The concentrations of all compounds except for IAA increased as temperature decreased and altitude increased. IAA showed an opposite response, that is, the concentrations of this phytohormone decreased with decreasing temperature and increasing altitude. We showed that temperature significantly affected the physiological attributes of Pedicularis punctata and Plantago major in the Himalayan region, which works as a proxy for understanding the plant responses to climate change. As per survival and risk assessment, underlying physiological mechanisms of plant response (understory plants) to changing environments (altitude and temperature ranges) revealed adaptation in the chilling environments. Further studies are needed to completely understand how the studied plants photosynthetic characteristics are affected by altitudinal gradient.

Camellia sinensis L. has long been used as a therapeutic agent for the Central nervous system (CNS) due to the presence of flavonoids. The present study aimed to evaluate the dose-dependent Neuropharmacological behavioral potential of Camellia sinensis seed and leaf extracts on mice. To evaluate the differential potential of leaf and seed extract various doses were prepared and examined in open field, head dip, rearing, cage cross, swimming and traction tests. One-way ANOVA set at P* < 0.05 followed by POST HOC LSD (P* < 0.01) was applied to evaluate the significant difference among the treatments. Herein both seed and leaf extract showed significant results at high doses. Interestingly leaf extract at high dose showed significant effect on mice CNS in open field and head dip test, while seed at high dose revealed significant stimulus on mice CNS in rearing, cage cross, swimming and traction tests. Overall results showed that seed produced more stimulant effect and less calmness as compared to leaf extract was. Tea leaves had already known as potential CNS stimulant drugs; current investigation suggests that tea seed can be used as an alternative CNS stimulant agent with more effective stimulant action.
RESUMEN
In spite of the remarkable achievements in the healthcare sector over recent decades, inequities in accessibility and affordability of these facilities coexist throughout Pakistan. Thus, we aimed to explore and document the cultural knowledge of herbal teas used medicinally by the local community members of Manoor Valley, Pakistan. Field investigations were undertaken during the summer season of 2015-2017, and cultural practices of medicinal plant usage for treating various ailments were gathered through interviews of the local inhabitants. Ethnomedicinal insights of the medicinal plants used in herbal teas were gained with different indexes. Our results revealed 27 plant species, comprising of herbs (70%), shrubs (26%), and trees (4%), which were used for treating 21 diseases. Plants belonged to 18 families: Asteraceae and Lamiaceae were the leading families used for treating diseases. Diarrhea and gas troubles were the most frequent diseases. Based on indexes values, Cannabis sativa was the dominant species used. The results revealed that 57% of medicinal uses are new to literature. This ethnomedicinal study is providing the first insights into the traditional medication system of Lesser Himalaya, Pakistan, through ethnomedicinal teas.
RESUMEN
Ethnobotany is the study of the direct interaction between plants and man in his culture. From time immemorial, man has been depending on Mother Nature for all his basic needs and plant diversity that existed around him always attracted his curiosity. Man's preliminary interest in plants started from his need for food, shelter, protection and then his attention shifted to the remedies for injuries and diseases. In fact, medicine and botany always had strong and close connections, as most of the modern medicines come from plant sources. The current venture reviews the developments and perspectives of ethnobotany in global scenarios. We have summarized the available literature and documentations regarding the historic background of ethnobotany. A survey of the literature survey reveals that plant resources were cited around the globe for curing almost all disease categories i.e. skin disorders, respiratory disorders, digestive disorders, urinary disorders, cardiac disorders, ophthalmic disorders, ear nose throat (ENT) disorders, excretory disorders, nervous disorders, immunity disorders and so on. The orally exchanged customary information/knowledge is in the hands of elders, and most of it can vanish after their deaths and could lead to the depletion of such imperative information. The ethnic society resources, like the folk asset in association with a nature of investigated and surveyed areas, can be conserved through documentation. The natural chemical compounds from plants may be screened and isolated. Plants with therapeutic uses should be tested in studies by using those isolated natural compounds in laboratories to screen and evaluate of plants metabolites with potential therapeutic uses.
