“…Forty-five eligible studies published between 1996 and 2016, including forty-one single-center [ 10 – 50 ] and four multi-center studies [ 51 – 54 ], were documented in this review. Among these studies, 12 were conducted in East China [ 10 – 21 ], 3 in South China [ 22 – 24 ], 4 in West China [ 25 – 28 ], 14 in North China [ 29 – 42 ], 3 in Taiwan [ 43 – 45 ], 4 in Hong Kong [ 46 – 49 ], and 1 in Macao [ 50 ].…”

High-risk HPV (hrHPV) is related to cervical carcinogenesis, although clinical data comparing the natural history and carcinogenic potential of type-specific HPV remain limited. Furthermore, the nationwide prevalence rates of overall and type-specific HPV among women with cervical precancerous lesions and cancer have not been reported. Here, a meta-analysis was performed for type-specific HPV distribution among 30,165 HPV-positive women, including 12,094 invasive cervical cancers (ICCs), 10,026 cervical intraepithelial neoplasia grade 2/3 (CIN2/3), 3246 CIN1, and 4799 normal cervices from 45 PCR-based studies. We found that HPV16 was the most common hrHPV type involved in cervical disease. The HPV16 positivity rate varied little across normal (22.7%) and CIN1 individuals (23.6%) but increased through the CIN2 (37.6%) and CIN3 patients (51.9%) to 65.6% in ICC cases. HPV16, 18, 35, 39, 45, and 59 were more frequent in ICC than CIN3, with ICC:CIN3 ratios ranging from 2.3 for HPV18 to 1.1 for HPV35/45. HPV31, 33, 52, and 58 were more frequent in CIN3 compared with normal cervices but less common in ICC compared with CIN3 (ICC:CIN3 ratios ranging from 0.6 for HPV58 and 0.4 for HPV52). The ICC:normal ratios were particularly high for HPV18, 52 and 58 in West China (4.1, 3.9 and 2.9, respectively) and for HPV45 and 59 in North China (1.6 and 1.1, respectively). In summary, this study is the most comprehensive analysis of type-specific HPV distribution in cervical carcinogenesis and could be valuable for HPV-based cervical cancer screening strategies and vaccination policies in China.

“…For example, in East Asia the most common HPV types in invasive cervical cancer were types 16, 18, 52, and 54, with prevalences of 57.1%, 17%, 11.4%, and 8.5%, respectively (32). In addition, according to a study in China, the most common and persistent high-risk HPV types were 16 (18.21%), 58 (13.2%), 18 (8.66%), 52 (7.06%), and 33 (34).…”

A series of solid-liquid phase change materials, thiourea derivatives, were prepared via condensation of thiourea with the respective carboxyl chlorides (lauroyl chloride, myristoyl chloride, and palmitoyl chloride) and were then characterized by using FT-IR, 1 H-NMR, differential scanning calorimetry (DSC), and thermogravimetric (TG) analysis. The thiourea derivatives (1,3-didodecanoyl thiourea, 1,3-ditetradecanoyl thiourea, and 1,3-dihexadecanoyl thiourea) were structurally symmetric and had long alkyl groups to crystallize. Thermal analysis by DSC and spectroscopic investigation by FT-IR spectroscopy were performed on the samples before and after thermal cycling tests to determine thermal reliability. The maximum latent heats of melting and freezing of the thiourea derivatives were found to be 114.6 and -110.0 J/g for 1,3didodecanoyl thiourea, 119.5 and -122.4 J/g for 1,3-ditetradecanoyl thiourea, and 148.8 and -142.7 J/g for 1,3-dihexadecanoyl thiourea after accelerated thermal cycling. A TG instrument was used to determine the starting point of degradation in the thiourea derivatives; it was found that the thiourea derivatives degraded at sufficiently higher temperatures than the expected utility temperatures.

“…Additionally, HPV mRNA and signal amplification can be detected via liquid-phase or in situ hybridization methods, as applied in Hybrid Capture 2 (HC2) (Qiagen Gaithersburg, MD, USA) [ 85 ]. Other validated commercial HPV tests used across the region include the Cervista HPV HR Test (Hologic, Madison, WI, USA) [ 140 ], careHPV Test (Qiagen Gaithersburg, MD, USA) [ 140 ], Linear Array (Roche Molecular Systems Inc., Pleasanton, CA, USA) [ 49 , 141 , 142 , 143 ], Cobas 4800 HPV Test (Roche Molecular Systems Inc., CA, USA) [ 140 , 144 ], Xpert HPV (Cepheid, CA, USA) [ 145 ], INNO-LiPA HPV Genotyping (Fujirebio, Gent, Belgium) [ 146 , 147 , 148 , 149 ], and Luminex Genotyping GP HR (Diassay, Netherlands) [ 150 ]. Additionally, there are wide varieties of commercial HPV genotyping kits that can simultaneously detect more than 20 HPV genotypes.…”

Human papillomavirus (HPV) infection remains one of the most prominent cancer-causing DNA viruses, contributing to approximately 5% of human cancers. While association between HPV and cervical cancers has been well-established, evidence on the attribution of head and neck cancers (HNC) to HPV have been increasing in recent years. Among the cancer-causing HPV genotypes, HPV16 and 18 remain the major contributors to cancers across the globe. Nonetheless, the distribution of HPV genotypes in ethnically, geographically, and socio-economically diverse East, Southeast, and South Asia may differ from other parts of the world. In this review, we garner and provide updated insight into various aspects of HPV reported in recent years (2015–2021) in these regions. We included: (i) the HPV genotypes detected in normal cancers of the uterine cervix and head and neck, as well as the distribution of the HPV genotypes by geography and age groups; (ii) the laboratory diagnostic methods and treatment regimens used within these regions; and (iii) the oncogenic properties of HPV prototypes and their variants contributing to carcinogenesis. More importantly, we also unveil the similarities and discrepancies between these aspects, the areas lacking study, and the challenges faced in HPV studies.
