Abstract

The goal of this research is to solve several one-dimensional partial differential equations in linear and nonlinear forms using a powerful approximate analytical approach. Many of these equations are difficult to find the exact solutions due to their governing equations. Therefore, examining and analyzing efficient approximate analytical approaches to treat these problems are required. In this work, the homotopy analysis method (HAM) is proposed. We use convergence control parameters to optimize the approximate solution. This method relay on choosing with complete freedom an auxiliary function linear operator and initial guess to generate the series solution. Moreover, the method gives a convenient way to guarantee the convergence of series solutions via the control parameter curve graphical method to rate the convergence and obtain the best solution. Decoding and analyzing potential Korteweg-de-Vries, Benjamin, and Airy equations, followed by convergence analysis to demonstrate the applicability of the method. By using the programs Mapel and Mathematica, the obtained results are very effective, accurate, and convergent to the exact solution after a few iterations, as shown in the tables and figures of this work.

Abstract

Carum carvi (Carium) or caraway is traditionally used for the treatment of several metabolic and non-metabolic disorders. In the current study, extracted oil, flavonoids, and alkaloids from the Carium were used to evaluate the effects of these components on blood lipid profile and heart regeneration from oxidative damages caused by hydrogen peroxide consumption. A total of 50 male BALB/c mice were used in this study with a body weight of 23-32 g. The animals were randomly divided into 5 groups (n=10). Group 1: The animals in this group were considered the control group and fed with a normal diet. Group 2: Hyperoxidative stress was induced in this group by giving hydrogen peroxide at a concentration of 1% into the drinking water for 6 weeks. After this period, they did not receive any treatments and only received saline solution by intraperitoneal (IP) injection once a day for 4 weeks. Group 3: Hyperoxidative stress was induced by hydrogen peroxide at a concentration of 1% for 6 weeks. All the animals in this group received 1.25 mg/kg body weight (B.W.) extracted oil from Caraway seeds for 4 weeks by IP injection once a day each week. Group 4: Hyperoxidative stress was induced by hydrogen peroxide at a concentration of 1% for 6 weeks. All the animals in this group received 61.28 mg/kg B.W. extracted flavonoids from Caraway seeds for 4 weeks by IP injection once a day each week. Group 5: Hyperoxidative stress was induced by hydrogen peroxide at a concentration of 1% for 6 weeks. All the animals in this group received 7.8 mg/kg B. W. extracted alkaloids from Caraway seeds for 4 weeks by IP injection once a day each week. The levels of glutathione and malondialdehyde were estimated in the liver and kidneys in the animals with cardiovascular disorders induced by hydrogen peroxide at a concentration of 1%. The results of the current study showed that the alkaloids had the greatest effect in reducing harmful total cholesterol and a complete recovery of the heart and aorta from atherosclerotic lesions through viewing the tissue sections.

Abstract

BACKGROUND: Increasing the dose intensity of cytotoxic therapy by shortening the intervals between cycles, or by giving individual drugs sequentially at full dose rather than in lower-dose concurrent treatment schedules, might enhance efficacy. METHODS: To clarify the relative benefits and risks of dose-intense and standard-schedule chemotherapy in early breast cancer, we did an individual patient-level meta-analysis of trials comparing 2-weekly versus standard 3-weekly schedules, and of trials comparing sequential versus concurrent administration of anthracycline and taxane chemotherapy. The primary outcomes were recurrence and breast cancer mortality. Standard intention-to-treat log-rank analyses, stratified by age, nodal status, and trial, yielded dose-intense versus standard-schedule first-event rate ratios (RRs). FINDINGS: Individual patient data were provided for 26 of 33 relevant trials identified, comprising 37 298 (93%) of 40 070 women randomised. Most women were aged younger than 70 years and had node-positive disease. Total cytotoxic drug usage was broadly comparable in the two treatment arms; colony-stimulating factor was generally used in the more dose-intense arm. Combining data from all 26 trials, fewer breast cancer recurrences were seen with dose-intense than with standard-schedule chemotherapy (10-year recurrence risk 28·0% vs 31·4%; RR 0·86, 95% CI 0·82-0·89; p<0·0001). 10-year breast cancer mortality was similarly reduced (18·9% vs 21·3%; RR 0·87, 95% CI 0·83-0·92; p<0·0001), as was all-cause mortality (22·1% vs 24·8%; RR 0·87, 95% CI 0·83-0·91; p<0·0001). Death without recurrence was, if anything, lower with dose-intense than with standard-schedule chemotherapy (10-year risk 4·1% vs 4·6%; RR 0·88, 95% CI 0·78-0·99; p=0·034). Recurrence reductions were similar in the seven trials (n=10 004) that compared 2-weekly chemotherapy with the same chemotherapy given 3-weekly (10-year risk 24·0% vs 28·3%; RR 0·83, 95% CI 0·76-0·91; p<0·0001), in the six t

Abstract

This work proposes a new angle of arrival method for tracking applications using compact omni-directional spiral antenna arrays. The impact of mutual coupling is considered within the covariance matrix calculation and then a suitable decoupling method is used to remove such effect. An urban area consisting of many buildings with different heights and characterized by various materials was modelled using Wireless In-Site Software to extract the impulse response of the channel between non-stationary locations of the transmitted target and the receiver antenna array. Orthogonal Frequency Division Multiplexing (OFDM) scheme based on wideband spectrum is integrated with the proposed angle of arrival to improve the estimation accuracy. MATLAB code is developed to simulate the above conditions and the experiment results are presented and discussed. &nbsp

Abstract

Background The administration of endocrine therapy for 5 years substantially reduces recurrence rates during and after treatment in women with early-stage, estrogen-receptor (ER)–positive breast cancer. Extending such therapy beyond 5 years offers further protection but has additional side effects. Obtaining data on the absolute risk of subsequent distant recurrence if therapy stops at 5 years could help determine whether to extend treatment. Methods In this meta-analysis of the results of 88 trials involving 62,923 women with ER-positive breast cancer who were disease-free after 5 years of scheduled endocrine therapy, we used Kaplan–Meier and Cox regression analyses, stratified according to trial and treatment, to assess the associations of tumor diameter and nodal status (TN), tumor grade, and other factors with patients’ outcomes during the period from 5 to 20 years. Results Breast-cancer recurrences occurred at a steady rate throughout the study period from 5 to 20 years. The risk of distant recurrence was strongly correlated with the original TN status. Among the patients with stage T1 disease, the risk of distant recurrence was 13% with no nodal involvement (T1N0), 20% with one to three nodes involved (T1N1–3), and 34% with four to nine nodes involved (T1N4–9); among those with stage T2 disease, the risks were 19% with T2N0, 26% with T2N1–3, and 41% with T2N4–9. The risk of death from breast cancer was similarly dependent on TN status, but the risk of contralateral breast cancer was not. Given the TN status, the factors of tumor grade (available in 43,590 patients) and Ki-67 status (available in 7692 patients), which are strongly correlated with each other, were of only moderate independent predictive value for distant recurrence, but the status regarding the progesterone receptor (in 54,115 patients) and human epidermal growth factor receptor type 2 (HER2) (in 15,418 patients in trials with no use of trastuzumab) was not predictive. During the study period from 5 to 20 years, the absolute risk of distant recurrence among patients with T1N0 breast cancer was 10% for low-grade disease, 13% for moderate-grade disease, and 17% for high-grade disease; the corresponding risks of any recurrence or a contralateral breast cancer were 17%, 22%, and 26%, respectively. Conclusions After 5 years of adjuvant endocrine therapy, breast-cancer recurrences continued to occur steadily throughout the study period from 5 to 20 years. The risk of distant recurrence was strongly correlated with the original TN status, with risks ranging from 10 to 41%, depending on TN status and tumor grade.

Abstract

BACKGROUND: Neoadjuvant chemotherapy (NACT) for early breast cancer can make breast-conserving surgery more feasible and might be more likely to eradicate micrometastatic disease than might the same chemotherapy given after surgery. We investigated the long-term benefits and risks of NACT and the influence of tumour characteristics on outcome with a collaborative meta-analysis of individual patient data from relevant randomised trials. METHODS: We obtained information about prerandomisation tumour characteristics, clinical tumour response, surgery, recurrence, and mortality for 4756 women in ten randomised trials in early breast cancer that began before 2005 and compared NACT with the same chemotherapy given postoperatively. Primary outcomes were tumour response, extent of local therapy, local and distant recurrence, breast cancer death, and overall mortality. Analyses by intention-to-treat used standard regression (for response and frequency of breast-conserving therapy) and log-rank methods (for recurrence and mortality). FINDINGS: Patients entered the trials from 1983 to 2002 and median follow-up was 9 years (IQR 5-14), with the last follow-up in 2013. Most chemotherapy was anthracycline based (3838 [81%] of 4756 women). More than two thirds (1349 [69%] of 1947) of women allocated NACT had a complete or partial clinical response. Patients allocated NACT had an increased frequency of breast-conserving therapy (1504 [65%] of 2320 treated with NACT vs 1135 [49%] of 2318 treated with adjuvant chemotherapy). NACT was associated with more frequent local recurrence than was adjuvant chemotherapy: the 15 year local recurrence was 21·4% for NACT versus 15·9% for adjuvant chemotherapy (5·5% increase [95% CI 2·4-8·6]; rate ratio 1·37 [95% CI 1·17-1·61]; p=0·0001). No significant difference between NACT and adjuvant chemotherapy was noted for distant recurrence (15 year risk 38·2% for NACT vs 38·0% for adjuvant chemotherapy; rate ratio 1·02 [95% CI 0·92-1·14]; p=0·66), breast cancer mortality (34·4% vs 33·7%; 1·06 [0·95-1·18]; p=0·31), or death from any cause (40·9% vs 41·2%; 1·04 [0·94-1·15]; p=0·45). INTERPRETATION: Tumours downsized by NACT might have higher local recurrence after breast-conserving therapy than might tumours of the same dimensions in women who have not received NACT. Strategies to mitigate the increased local recurrence after breast-conserving therapy in tumours downsized by NACT should be considered-eg, careful tumour localisation, detailed pathological assessment, and appropriate radiotherapy.

Abstract

The social difficulties have been grown worldwide, in particular in the developing countries, under which the Arab countries are classified and form an important part thereof. This era is characterized by the era of giant organizations (The incorporated companies) as well as known the era of globalization, where the whole world becomes a small town in the light of the modern communication means. To avoid efforts scattering, losing accountabilities and resources, all individuals of the Arab Society must cooperate, to confront these challenges. This requires the development of concept and then the role which can be played by the Business Organizations in both aspects; the economic activity and social activity, in the consideration that these organizations have rights and at the same time commitments towards the society. Due to the fact that these organizations enjoy the wealth of the society, including the various natural, material and human resources, so they must contribute in solving its difficulties within their capabilities and capacity. This will lead us to the position of recognition the social responsibilities side by side with the special responsibility (financial) of the organizations owners.

Abstract

The purpose of this study was to examine the effects of Cerastes cerastes gasperetti crude venom (CCV) on free radical (FR) production and biological antioxidant potential (BAP). Thirty male rats, matched with age and weight, were divided randomly into three groups: control (C), negative control (NC), and experimental (E). Animals in the control group served as control for needlestick and venom injection. Animals in the negative control group, which served as control for venom-induced effects, were injected intraperitoneally (IP) with saline for 8 days, whereas animals of the experimental group were injected IP with crude CCV, at a dose of 1/4 LD50, for the same period. All animals of the three groups remained under normal laboratory and dietary conditions. Blood samples were collected by heart puncture technique and were analyzed immediately for FRs and BAP. ANOVA analysis indicated a significant difference (p < 0.05) among group means. Tukey-Kramer multiple comparisons showed that FRs increased significantly (p < 0.05) in the NC group, implying that needlestick during injection of saline for 8 days caused internal organ injury sufficient enough to induce reactive oxygen species (ROS) generation. Surprisingly, there were no significant (p > 0.05) changes in FRs in the E group as compared with the C group, which indicates that CCV counteracted the effects induced by ROS. BAP increased significantly (p < 0.05) in the E group as compared with the NC group, reflecting the activation of some antioxidant enzymes. Linear regression of FRs on BAP was significant (p < 0.05) in both the C and E groups. Based on the results of this study, it can be concluded that the CCV contains biochemical factors that activate antioxidant enzymes, as evident by elevation in the BAP that depresses ROS formation.

Abstract

Background Increasing the dose intensity of cytotoxic therapy by shortening the intervals between cycles, or by giving individual drugs sequentially at full dose rather than in lower-dose concurrent treatment schedules, might enhance efficacy. Methods To clarify the relative benefits and risks of dose-intense and standard-schedule chemotherapy in early breast cancer, we did an individual patient-level meta-analysis of trials comparing 2-weekly versus standard 3-weekly schedules, and of trials comparing sequential versus concurrent administration of anthracycline and taxane chemotherapy. The primary outcomes were recurrence and breast cancer mortality. Standard intention-to-treat log-rank analyses, stratified by age, nodal status, and trial, yielded dose-intense versus standard-schedule first-event rate ratios (RRs). Findings Individual patient data were provided for 26 of 33 relevant trials identified, comprising 37 298 (93%) of 40 070 women randomised. Most women were aged younger than 70 years and had node-positive disease. Total cytotoxic drug usage was broadly comparable in the two treatment arms; colony-stimulating factor was generally used in the more dose-intense arm. Combining data from all 26 trials, fewer breast cancer recurrences were seen with dose-intense than with standard-schedule chemotherapy (10-year recurrence risk 28·0% vs 31·4%; RR 0·86, 95% CI 0·82–0·89; p Interpretation Increasing the dose intensity of adjuvant chemotherapy by shortening the interval between treatment cycles, or by giving individual drugs sequentially rather than giving the same drugs concurrently, moderately reduces the 10-year risk of recurrence and death from breast cancer without increasing mortality from other causes.

Variability among 74 genotypes for thirty-seven traits (29 quantitative and 8 qualitative) were studied to ascertain the population structure of the Bunium persicum . Among the agro-morphological traits, wide range of variability was recorded in tuber shape, tuber colour, seed shape, seed colour, growth habit, leaf shape, leaf colour, umbel shape, umbel colour, plant height (22.90-96.52 cm), primary branches plant -1 (1-6), umbel diameter of primary umbel (6.17 - 13.67 cm), number of primary umbels plant -1 (1-12), umbels plant -1 (8-40), seed yield per plant (0.55-13.10 g), essential oil content (3.2-9.3 %) etc. Significant and positive association was observed between number of seeds primary -1 umbel (r = 0.91), plant height (r = 0.65), number of seeds primary -1 umbel (0.52), number of seeds primary -1 umbel (0.43), number of seeds secondary -1 umbel (0.38) with number of umblets secondary -1 umbel. Cluster analysis classified the genotypes with different geographical origin into two major clusters and sub-clusters. Cluster-I comprises of 50 genotypes and cluster - II of 24 genotypes while the genotype SRS-KZ-189 from Kargil population was separated as an individual sub-group. Principal component (PC1) and (PC2) harbors accounted 20.2% and 14% of total variation. Variability of Kalazeera genotypes would facilitate the plant breeders to implement and design various crop improvement programme in future., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper.The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2023 The Author(s).)

Abstract

Carum carvi (Carium) or caraway is traditionally used for the treatment of several metabolic and non-metabolic disorders. In the current study, extracted oil, flavonoids, and alkaloids from the Carium were used to evaluate the effects of these components on blood lipid profile and heart regeneration from oxidative damages caused by hydrogen peroxide consumption. A total of 50 male BALB/c mice were used in this study with a body weight of 23-32 g. The animals were randomly divided into 5 groups (n=10). Group 1: The animals in this group were considered the control group and fed with a normal diet. Group 2: Hyperoxidative stress was induced in this group by giving hydrogen peroxide at a concentration of 1% into the drinking water for 6 weeks. After this period, they did not receive any treatments and only received saline solution by intraperitoneal (IP) injection once a day for 4 weeks. Group 3: Hyperoxidative stress was induced by hydrogen peroxide at a concentration of 1% for 6 weeks. All the animals in this group received 1.25 mg/kg body weight (B.W.) extracted oil from Caraway seeds for 4 weeks by IP injection once a day each week. Group 4: Hyperoxidative stress was induced by hydrogen peroxide at a concentration of 1% for 6 weeks. All the animals in this group received 61.28 mg/kg B.W. extracted flavonoids from Caraway seeds for 4 weeks by IP injection once a day each week. Group 5: Hyperoxidative stress was induced by hydrogen peroxide at a concentration of 1% for 6 weeks. All the animals in this group received 7.8 mg/kg B.W. extracted alkaloids from Caraway seeds for 4 weeks by IP injection once a day each week. The levels of glutathione and malondialdehyde were estimated in the liver and kidneys in the animals with cardiovascular disorders induced by hydrogen peroxide at a concentration of 1%. The results of the current study showed that the alkaloids had the greatest effect in reducing harmful total cholesterol and a complete recovery of the heart and aorta from atherosclerotic lesions through viewing the tissue sections., Competing Interests: The authors declare that they have no conflict of interest.

Abstract

Introduction: In Oman, the ""transition" of health care of adolescents to adult care occurs at a young age, like many other GCC countries for cultural reasons. In order to address this concern, this study was conducted to determine the transition readiness skills of adolescents and young adults with childhood onset rheumatic diseases using a cross-cultural adaptation of the UNC TRxANSITION scale., Methods: We used a professionally translated/back translated, provider-administered UNC TR x ANSITION Scale. This 32-question scale measures HCT in 10 domains including knowledge about diagnosis or treatment, diet, reproductive health, school/work, insurance, ability to self-manage and identification of new health providers. The maximum transitional score of 10, was categorized as low (1-4), moderate (4 - 7) and high (7 -10) transitional readiness scores., Results: We enrolled 81 Omani adolescents and young adults (AYA) with chronic childhood onset rheumatic diseases. The cohort consisted of 79% females, with mean age of 15.8 years (± 3.53) and mean disease duration of 6.95 years (± 4.83). Our cohort's overall mean score is low 5.22 (±1.68). Only 14.8% of the cohort achieved a high transition score (≥7). Significant direct relationship was observed between age and the mean transition readiness score (r = .533, P < .001). The mean transition readiness score in the younger age group (10-13 years) was 4.07 (±1.29), the middle age group (14-18 years) was 5.43 (±1.27), while the older age group (19-21 year), was 6.12 (±1.81). Mean transition score of youngest age group was found to be significantly lower than the other two age groups (p = .003)., Conclusion: Overall, the transition readiness of AYA in Oman is low compared to other western countries indicating the need to initiate a health care transition preparation program for patients with chronic diseases across the country. In addition, we need to establish regional guidelines to address the transfer and transition policies to be in line to international recommendations. As transition continues after transfer, and is preferably guided by adolescent developmental status rather than chronological age, it would be preferable to refer to the transition and transfer policies 9rather than transitional age policy) to be in line to international recommendations., (© 2022.

Abstract

Diplometopon zarudnyi, a worm lizard belongs to amphisbaenia under trogonophidae family. This species exists in limited areas of the Arabian Peninsula and is an oscillating digger found in sub-surface soils. The present study aimed to investigate the sperm tail differentiation in D. zarudnyi. Ten male adults of D. zarudnyi were collected from Riyadh during April-May 2011. To study the sperm tail at the ultrastructural level the testes were fixed in 3% glutaraldehyde, than post fixed in 1% osmium tetaroxide followed by dehydration in ethanol grades; samples were cleared in propylene oxide and embedded in resin. Tail formation begins by the moving of centrioles and mitochondria towards the posterior pole of sperm head. Simultaneously many microtubules of the midpiece axoneme were enclosed by a thick layer of granular material. Mitochondria of midpiece lie alongside the proximal centriole which forms a very short neck region and possess tubular cristae internally and concentric layers of cristae superficially. During this course a fibrous sheath surrounds the axoneme of mid and principal piece. At the end dissolution of longitudinal manchette takes place. The mitochondria then rearrange themselves around the proximal and distal centrioles to form a neck region. Later, the fibrous sheath surrounds the proximal portion of the flagella. This part along with sperm head of D. zarudnyi provides a classical model that could be used in future for evolutionary and phylogenetic purposes of class reptilia.

Abstract

The reproductive biology of the horned viper, Cerastes cerastes gasperettii, in Riyadh region of Saudi Arabia was investigated over a period of one year. Study of reproductive cycle of male and female C. c. gasperettii revealed that the breeding season is relatively short (April and May). Thereafter females laid eggs by mid of July and hatching probably had taken place by the end of September. No activity was observed during winter, this may indicate just a single clutch per year. Relative testis weight to body weight was drastically increased ([Formula: see text] = 0.88%) during the peak of reproductive activity (May) where maximal expansion of seminiferous tubules was also attained during April and May ([Formula: see text] = 209 μm and 191 μm, respectively). Likewise, the ovarian activity was the highest during May where ovarian parameters were greater in terms of relative ovarian weight to body weight and ova diameter being 0.46% and 2.29 mm, respectively. Fat body weight was increased drastically just before the peak of reproductive activity then started to decline during June. It could be concluded that the harsh desert conditions and similar environments certainly affect reproductive activity of Saudi Arabian reptiles including snakes.

Abstract

Objectives: Discharge against medical advice (DAMA) is a major problem in healthcare delivery as it can complicate the health problems from which patients are suffering. The aim of this study was to understand DAMA among children in a tertiary teaching hospital in Oman and to evaluate the documentation of the events in the medical records., Methods: A retrospective survey of the medical records of patients discharged against medical advice over a two-year interval was performed (2004-2006)., Results: Of the 11,802 admissions, there were 38 cases of DAMA, giving a prevalence rate of 0.32%. In 39.5% of the cases, the discharge happened within 24 hours of hospital admission. The majority of the cases were infants (n = 24; 63.25%). The diagnosis at discharge in some cases included life-threatening conditions. However, in 57.9% of the cases, the reasons for DAMA were neither reported nor documented in the patients' medical records., Conclusion: Although the results of this study yielded a low prevalence rate compared to the rates reported in other studies, the occurrence of DAMA for children in a tertiary hospital is a distressing phenomenon. It was evident that the documentation of the DAMA process was poor. More studies should be conducted to understand the details of the problem. Policies should be established and implemented in order to attempt to reduce DAMA among child patients and to protect them from the consequences of such discharges.

Abstract

A 5-month-old child, previously healthy, was hospitalized with frequent episodes of tonic seizures. The seizures were controlled with antiepileptic medication. However, the parents did not continue medications after discharge from the hospital. The child was admitted several times with breakthrough seizures. Over time the seizures became refractory to treatment. Neurometabolic work up and imaging studies for uncontrolled seizures revealed non-accidental head injury (shaken baby syndrome) as the underlying cause. His first EEG was normal and changed from normal to an epileptic encephalopathy pattern during his several admissions for uncontrolled seizures. From a normal child at the first admission, the child was severely regressed at the last admission. The present paper highlights the evolution of EEG changes in a child with non-accidental head injuries. This report also highlights considering non-accidental head injury as the underlying cause in younger children presenting with unexplained epileptic encephalopathy.

Abstract

Use of molecular markers for identification of protected species offers a greater promise in the field of conservation biology. The information on genetic diversity of wildlife is necessary to ascertain the genetically deteriorated populations so that better management plans can be established for their conservation. Accurate classification of these threatened species allows understanding of the species biology and identification of distinct populations that should be managed with utmost care. Molecular markers are versatile tools for identification of populations with genetic crisis by comparing genetic diversities that in turn helps to resolve taxonomic uncertainties and to establish management units within species. The genetic marker analysis also provides sensitive and useful tools for prevention of illegal hunting and poaching and for more effective implementation of the laws for protection of the endangered species. This review summarizes various tools of DNA markers technology for application in molecular diversity analysis with special emphasis on wildlife conservation.

Abstract

Molecular marker techniques have been widely used for cultivar identification of inbred date palms (Phoenix dactylifera L.; Arecaceae) and biodiversity conservation. Isolation of highly pure DNA is the prerequisite for PCR amplification and subsequent use such as DNA fingerprinting and sequencing of genes that have recently been developed for barcoding. To avoid problems related to the preservation and use of liquid nitrogen, we examined sterile sand for grinding the date palm leaves. Individual and combined effects of sodium chloride (NaCl), polyvinylpyrrolidone (PVP) and lithium chloride (LiCl) with the cetyltrimethylammonium bromide (CTAB) method for a DNA yield of sufficient purity and PCR amplification were evaluated in this study. Presence of LiCl and PVP alone or together in the lysis buffer did not significantly improve the DNA yield and purity compared with the addition of NaCl. Our study suggested that grinding of date palm leaf with sterile sand and inclusion of NaCl (1.4 M) in the lysis buffer without the costly use of liquid nitrogen, PVP and LiCl, provides a DNA yield of sufficient purity, suitable for PCR amplification.
