An inventory planning problem for time-varying linear demand and parabolic holding cost with salvage value
In this manuscript, a model is proposed for the inventory planning problem with items which deteriorate linearly with respect to time. The concept of salvage value for deteriorated items is considered and incorporated in this model. The solution procedure of proposed optimization model is…

Solution of Extended Multi-Objective Portfolio Selection Problem in Uncertain Environment Using Weighted Tchebycheff Method
In this paper, a mathematical model for an extended multi-objective portfolio selection (EMOPS) problem is explored with liquidity considered as another objective function besides the risk and return. The model is mathematically formulated in an uncertain environment. The concerned uncertainty is…

LncRNAs Regulatory Networks in Cellular Senescence
Long noncoding RNAs (lncRNAs) are a class of transcripts longer than 200 nucleotides with no open reading frame. They play a key role in the regulation of cellular processes such as genome integrity, chromatin organization, gene expression, translation regulation, and signal transduction. Recent…

Mnemonics for diagnostic criteria of DSM V mental disorders: a scoping review
A multitude of psychiatric disorders have been described in classification systems like the Diagnostic and Statistical Manual of Mental Disorders Fifth Edition (DSM V). Diagnosing a specific mental disorder requires memorising specific symptom criteria, and their improper recall may result in…

AGO-RBP crosstalk on target mRNAs: Implications in miRNA-guided gene silencing and cancer
MicroRNAs (miRNAs) and RNA-binding proteins (RBPs) are important regulators of mRNA translation and stability in eukaryotes. While miRNAs can only bind their target mRNAs in association with Argonaute proteins (AGOs), RBPs directly bind their targets either as single entities or in complex with…

Cardiovascular and airway consideration in pediatric thoracic anterior mediastinal mass
Mediastinal tumors are common neoplasms among the pediatric population. The symptoms may be due to the direct compression effects on the surrounding structures or “B” like symptoms of specific lymphomas or due to paraneoplastic syndrome. The cardiovascular and respiratory consequences of the…

Drug resistance mechanisms in cancers: Execution of pro-survival strategies
One of the quintessential challenges in cancer treatment is drug resistance. Several mechanisms of drug resistance have been described to date, and new modes of drug resistance continue to be discovered. The phenomenon of cancer drug resistance is now widespread, with approximately 90% of…

Sexual dysfunction in male patients with alcohol dependence syndrome – A case-control study
Introduction and Aim: Alcohol may foster the initiation of sexual activity by removing inhibitions, but it impairs performance in the long-run, which leads to marked discomfort and relationship problems. These problems, in turn, would amplify alcohol misuse. Some studies have looked into sexual…

Psychogenic non-epileptic seizures: Why anaesthesiologist should know?
A 19-year-old primigravida underwent caesarean section under spinal anaesthesia. She presented with seizures on 7th post-operative day. All the common etiological factors for seizures were ruled out. We found out that the seizures were due to a psychiatric condition called 'psychogenic…

A profit maximization model for sustainable inventory under preservation technology and linear time-dependent holding cost
This paper presents sustainable inventory model with constant deterioration rate when holding cost is time dependent. Demand rate is price and stock dependent. Preservation technology and carbon emission are considered for more sustainable approach. Shortages are allowed and are fully backlogged…

Ambu® aScope™ as a Gastroscope in Emergency Situations: A Report of Two Cases
The working principles of the bronchoscope and gastroscope differ in the fact that the anatomical structures which they interrogate have different collapsibility. The trachea and bronchi are supported by cartilage which make then non-collapsible, hence no external support is needed to visualise…

Sporadic right ventricle rhabdomyoma in an adult without tuberous sclerosis
Cardiac rhabdomyoma is a rare benign tumor of the pediatric age group which usually regresses by the age of 2 years. Cardiac rhabdomyoma in adults is still a rarer disease. It is usually associated with tuberous sclerosis. Patients with cardiac rhabdomyoma will usually be asymptomatic and detected…

A partial backlogging inventory model for deteriorating items with time-varying demand and holding cost: An interval number approach
This paper proposes a differential equation inventory model that incorporates partial backlogging and deterioration. Holding cost and demand rate are time dependent. Shortages are allowed and assumed to be partially backlogged. Two versions are presented, the first one with deterministic values of…
