A Strong Designated Verifiable DL Based Signcryption Scheme
Mohanty, Sujata,Majhi, Banshidhar Korea Information Processing Society 2012 Journal of information processing systems Vol.8 No.4
This paper presents a strong designated verifiable signcryption scheme, in which a message is signcrypted by a signcryptor and only a specific receiver, who called a "designated verifier", verifies it using his own secret key. The scheme is secure, as an adversary can not verify the signature even if the secret key of the signer is compromised or leaked. The security of the proposed scheme lies in the complexity of solving two computationally hard problems, namely, the Discrete Logarithm Problem (DLP) and the Integer Factorization Problem (IFP). The security analysis of the scheme has been done and it is proved that, the proposed scheme can withstand an adaptive chosen ciphertext attack. This scheme can be very useful in organizations where there is a need to send confidential documents to a specific recipient. This scheme can also be applicable to real life scenarios, such as, e-commerce applications, e-banking and e-voting.

Proteomic Signatures in Spermatozoa Reveal the Role of Paternal Factors in Recurrent Pregnancy Loss
Gayatri Mohanty,Soumya Ranjan Jena,Jasmine Nayak,Sujata Kar,Luna Samanta 대한남성과학회 2020 The World Journal of Men's Health Vol.38 No.1
Purpose: To identify the paternal factors responsible for aberrant embryo development leading to loss of foetus in recurrent pregnancy loss (RPL) through proteomic analysis of ejaculated spermatozoa. Materials and Methods: This prospective study consisted of male partners of RPL patients (n=16) experienced with two or more consecutive unexplained miscarriages and with no female factor abnormality as revealed by gynaecologic investigation including karyotyping and age matched fertile healthy volunteers (n=20). All samples were collected during 2013 to 2015 after getting institutional ethical approval and written consent from the participants. Seminal ejaculates were collected by masturbation after 2 to 3 days of sexual abstinence and analyzed according to World Health Organization 5th criteria 2010. Two-dimensional difference gel electrophoresis followed by mass spectrophotometric analysis was used to identify differentially expressed proteins (DEPs). Western blotting was used for validation of the key proteins. Results: The data identified 36 protein spots to be differentially expressed by more than 2-fold change with p<0.05 considered as significant. Matrix-assisted laser desorption/ionization time of flight/mass spectrometry identified GPx4, JIP4, ZN248 to be overexpressed while HSPA2, GSTM5, TF3C1, CC74A was underexpressed in RPL group. Western blot analysis confirmed the differential expression of key redox associated proteins GPx4 and HSPA2 in the RPL group. Functional analysis revealed the involvement of key biological processes that includes spermatogenesis, response to oxidative stress, protein folding and metabolic process. Conclusions: The present study provides a snapshot of the altered protein expression levels consistent with the potential involvement of the sperm chromatin landscape in early embryonic development.

CLB-ECC: Certificateless Blind Signature Using ECC
( Sanjeet Kumar Nayak ),( Sujata Mohanty ),( Banshidhar Majhi ) 한국정보처리학회 2017 Journal of information processing systems Vol.13 No.4
Certificateless public key cryptography (CL-PKC) is a new benchmark in modern cryptography. It not only simplifies the certificate management problem of PKC, but also avoids the key escrow problem of the identity based cryptosystem (ID-PKC). In this article, we propose a certificateless blind signature protocol which is based on elliptic curve cryptography (CLB-ECC). The scheme is suitable for the wireless communication environment because of smaller parameter size. The proposed scheme is proven to be secure against attacks by two different kinds of adversaries. CLB-ECC is efficient in terms of computation compared to the other existing conventional schemes. CLB-ECC can withstand forgery attack, key only attack, and known message attack. An e-cash framework, which is based on CLB-ECC, has also been proposed. As a result, the proposed CLB-ECC scheme seems to be more effective for applying to real life applications like e-shopping, e-voting, etc., in handheld devices.

An overview of Acne Vulgaris (Busoor Labaniya)
Mehnaz, Mehnaz,Shamsi, Yasmeen,Akhtar, Md. Wasi,Zaidi, Sahar,Mohanty, Sujata,Ahmad, Sayeed Cellmed Orthocellular Medicine and Pharmaceutical 2022 셀메드 (CellMed) Vol.12 No.2
Acne vulgaris is a common dermatological condition affecting the pilosebaceous units and having a multifactorial etiology. In Unani terminology, acne vulgaris is referred as Busoor Labaniya, characterized by white lesions on the face, nose, and cheeks; on squeezing, release cheesy material. In conventional medicine, mild cases are best addressed with topical regimens, but more severe cases require systemic medications. Retinoids (retinoic acid, adapalene, isotretinoin, tazarotene), benzoyl peroxide, clindamycin, erythromycin, and azelaic acid are a few examples of topical medications, whereas systemic drugs include antibiotics (Doxycycline, minocycline, erythromycin, azithromycin). In the Unani System of Medicine, numerous single and compound drugs have been used to treat Busoor Labaniya. These drugs are considered harmless and do not have any major side effects. In Unani system of medicine, acne vulgaris is effectively managed with natural medicines as well as therapeutic regimens with minimal side effects even after long-term usage. Acne vulgaris is usually treated with systemic blood purifiers along with topical Unani drugs. Hence, clinical studies with proper scientific parameters are needed to be conducted to establish and validate their efficacy in the prevention and control of acne vulgaris.
