Keratin 19 as a prognostic marker and contributing factor of metastasis and chemoresistance in high‐grade serous ovarian cancer

open access: yesMolecular Oncology, EarlyView.
Keratin 19 (KRT19) is overexpressed in high‐grade serous ovarian cancer with high levels of Kallikrein‐related peptidases (KLK) 4–7 and is associated with poor survival. In vivo analyses demonstrate that elevated KRT19 increases peritoneal tumour burden.

Analysis of JS-contractions with applications to fractional boundary value problems

open access: yesJournal of Inequalities and Applications, 2023
In this article, we modify JS-contractions by weakening the conditions on the function θ, where θ : ( 0 , ∞ ) → ( 1 , ∞ ) $\theta : ( 0,\infty ) \rightarrow ( 1,\infty ) $ is a strictly increasing function.

A generalized weak contraction principle with applications to coupled coincidence point problems

open access: yes, 2013
In this paper we establish some coincidence point results for generalized weak contractions with discontinuous control functions. The theorems are proved in metric spaces with a partial order.

Polarization‐resolved femtosecond Vis/IR spectroscopy tailored for resolving weak signals in biological samples using minimal sample volume

open access: yesFEBS Open Bio, EarlyView.
Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

A new approach to multivalued nonlinear weakly Picard operators

open access: yesJournal of Inequalities and Applications, 2019
The notion of nonlinear (Fs,L) $(\mathcal{F}_{s}, \mathcal{L})$-contractive multivalued operators is initiated and some related fixed point results are considered. We also give an example to show the validity of obtained theoretical results.

Relation-Theoretic Weak Contractions and Applications

open access: yesMathematics, 2023
In this article, we discuss the relation-theoretic aspects of weakly contractive mappings to prove fixed point results in the setting of metric spaces endowed with a certain binary relation. We also provide an example and an application to validate of our results.

Screening and epitope characterization of Nidogen‐2‐specific nanobodies

open access: yesFEBS Open Bio, EarlyView.
Camel immunization and phage display were employed to generate high‐affinity VHH nanobodies against Nidogen‐2. After library construction, biopanning, ELISA screening, sequencing, and recombinant expression, selected nanobodies were purified and characterized, leading to the preliminary exploration of a nanobody‐based sandwich ELISA for specific ...

Spinal Cord Infarction Versus Idiopathic Transverse Myelitis: Clinical, Radiological, and Functional Insights From a Retrospective Cohort Study

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Introduction Spinal cord infarction (SCI) is a rare but devastating myelopathy, characterized by a high disability rate and an unfavorable prognosis. It has often been underdiagnosed and misdiagnosed as idiopathic transverse myelitis (ITM). This study aimed to describe the clinical features, radiological biomarkers, treatments, and functional ...

Ri-sets, pseudo-contractibility and weak contractibility on hyperspaces of continua

open access: yesGlasnik matematički, 2018
In this paper we discuss the notions of pseudo-contractibility and weak contractibility on hyperspaces of (Hausdorff) continua. Also we prove that if a continuum X contains an Ri-set then it is not pseudo-contractible. As a consequence we have that the existence of an Ri-set in a continuum X implies non(pseudo)-contractibility of some hyperspaces.

Common Fixed Point Results via Set-Valued Generalized Weak Contraction with Directed Graph and Its Application

open access: yes, 2022
In this manuscript, common fixed point results for set-valued mapping under generalized ψ,ϕ1 and ψ,ϕ2 weak contraction without using Hausdorff metric are studied endowing with a graph. To demonstrate the authenticity of the established result, a suitable
